Hi Mr Flynn thanks so much for this video it helped me figure out what I want to do for my IA. I liked the idea of a volume of a revolution, im going to use that and the student that did it on the airplane engine, what was his real world application if you dont mind me asking?
Hi Mr Flynn thanks so much for the video, it inspired me to pick the topic i will mention later. i am currently in math hl and have my ia topic which is dealing with the forgetting curve. i am trying to find how age and disorders such as dementia effect the curve. I have gathered my data but i am unsure of what topics from math hl you think i might be able to include. since the graph is exponential decay i was thinking of using integration to find the area under the graph/ the difference in retention capabilities of the different age groups/disorders. however i don't think this will be enough.
Hey Mr.Flynn, thank you for taking the time to make videos like these for other ib students. I'm in HL AA and I was wondering if doing an IA that models geometry dash and the music that plays in the background would be enough HL math. I believe I'd calculate the curve that the square goes on with each jump and maybe graphing the changes in pitch to see during which pitch or shift a jump is necessary. I also had another idea but was not sure about the math that would go into it, the perfect teapot to produce laminar flow and prevent spillage when pouring. I'm sorry if this is an inconvenience
Hi Mr Flynn, thanks so much for this video, it really cleared a lot of things up. Coincidentally, my idea for my IA was F1, do you have any other suggestions for more specific topics within F1?
I like the thought of modelling the velocity against time of two different cars passing through a specific turn and then compare. You can use calculus to find max and min velocity along with acceleration. Talk about which car is better. Which driver is better. That's just one idea. Have a think of a few more and I will let you know if they might work .
I need to find a topic for my math ia, i have ai hl, and i was thinking maybe i could compare a bowling strike in real life compared to in wii sports and compare them using quadratic modelling, but i don’t think it will reach hl, could i possibly include vectors in the context of the position of the bowling ball and the pins?
Hi Mr Flynn, thank you for this video. I found it so helpful and useful! However, i have a question. I am planning on finding the volume of revolution or maybe using ellipse modelling for a rugby ball but currently I have no idea on what to relate it to. Do you think if i relate it with the spinning of the ball would be a good idea? or do you have any other better idea regarding the volume of revolution or ellipse modelling?
Volume of an ellipsoid is good. Really it's you that needs to come up with a good reason for doing it. A common idea might be to see which is bigger the volume of a football or rugby ball. You might want to see is the ratio between a size 5 and size 4 football the same as the ratio between a size 5 and size 4 rugby ball. Let me know what you come up with.
Hello Mr Flynn, thank you for the video! i really needed it and i do find it useful. But, to be honest, I still havent gotten any idea for my ia math topic. Every video that I watched mention about finding a topic based on my interest, but I still couldnt find one until now. I dont think that all of my interests have something to do with math, so I am having a very hard time to think of a topic. I really need guidance, Mr Flynn.
What are your interests? Remember it doesn't have to be your hobby or passion. For example we are all interested in the corona virus at the moment so perfectly reasonable for anyone to do an IA on that. No doubt there will be a lot IA's on covid this year. Also a really good IA I had which you might have seen was finding the area of the school. I wouldn't say that my student was passionately interested in the area of the school but he did genuinely wonder 'how big is the wall' and then became very interested in the mathematics involved rather than the final answer.
@@MrFlynnIB Mr Flynn, Im back! I already have an idea in mind but im thinking of asking for your opinion first. Im thinking of modelling fruit (one of these options) like watermelon, coconut, lemon, or maybe banana using the ellipse equation. The aim for this is to find the volume of its flesh, the number of people that can be served to, the amount of juice that can be produced and served from the fruit. what do you think about this idea, mr flynn?
Hi Mr Flynn, i want to ask you opinion on my math ia idea. I am taking MAA HL so i wonder if my topic is suitable or not. I plan to find the surface area and volume of two bottle of mineral water from two different brands. I am planning on using volume and surface area of revolution. The surface area is used to determine which one is more eco friendly and use less plastic. The volume is for determining which one consume less space and easier to store when traveling. Do you think this topic is suitable for MAA HL
Hi Arif. Yes this is a good and popular idea. Mathematics is definitely HL level. The only thing I would say is that I have seen this topic many times so try and make it original with an interesting aim.
Hi Mr. Flynn. Thank you for all your guidance regarding the IA. I’m a math AI SL student and you said that correlations IA’s don’t score as high as other IA’s. I’m doing mine in correlation, do you have any ideas or tips which could help me further increase my grade even while doing a correlation IA ?
Hi Ayesha. The main reason students don't score well with correlation IAs is that they usually sub numbers into a formula without really showing understanding. For sure it is possible to score well but you have to show the reader that you have a really good understanding of what you are doing. Explain the formula for r, where it comes from and why it works.
Thank you Mr. Flynn, I could certainly do that. If I am correlating two factors, what other tips would you suggest to score a high mark ?. Should I use a chi square test on the data or fo you have any other perspectives would you recommend. I am in quite a pickle as I regret choosing this topic but I am trying to do it to the best of my ability.
Hello mr flynn, do you have any ideas of what I could optimize? I have seen the process for a soda can, a cylinder, but have not yet encountered anything else

@@MrFlynnIB differential calculus for the most part, but i feel i could also include some trignometry in the second topic, do you think it would be enough as i am doing hl?
@@shri2820 Both have potential for sure but I don't really understand what you are going to do. How exactly are you going to use differential calculus to make weather predictions? and how exactly are you going to find the optimal route of travel for a rocket?
Hi Mr Flynn, I just want to say I appreciate a lot putting the effort to help us get through the IA. I’m exactly the student that has jumped right into the correlation between life expectancy and GDP per capita. However, I’m doing it with education and how some other social factors may also influence its correlation. I was never satisfied with the idea and never saw a future with it. I’m still lost and not sure what to do, but I now with the right topic I could do my IA in a very short period of time. Hence, do you have any suggestions? Should I change my topic (Because I’m aiming for a high 6 or 7)? Perhaps with optimization? (I’m math HL A&A by the way).
I would probably suggest you change if you are HL and looking for a 6 or 7. Have you watched part 7 and and part 8. A lot of ideas there. Anything that interests you?
@Mr. Flynn IB Wow, thank you so much for your early reply. I have watched part 7 and part 8, I was really interested in doing something with the Voronoi diagrams (some kind of situation of placing in the most efficient places some health care centers that would prevent the risk of patients dying during their way to the hospital and perhaps do some probability as well). I also had a meeting with my math teacher today and told me to stick with the same topic, if I explain step by step the linear regression and coefficient formula, add all kinds of tests (e.g. T-test, Chi-square test), and go then more in depth with other kinds of factors (more into comparing their functions in relation to life expectancy) I should be fine to get a 6 or 7. However, I'm not sure if this is really the case, what you do think?
@@manve5652 You can get a 6 or 7 with any topic in the course if it is done well enough. Life expectancy v GDP is probably the most done topic of all time which is why I'm not a big fan. It's up to you. If you genuinely interested in it, go for it.
Dear Mr Flynn, actually I have confusion in choosing which MAA HL IA topic that I should choose, at first I thought of having modelling for hand sanitizer with syringe inside ( the syringe is used to take out the volume of hand sanitizer to be used for each day) as my IA project, the second one is by making formula of minimum volume of hand sanitizer used for each day, which one do you think is more appropriate, or should i rethink about both of it again?
Interesting. I like both but I'm not clear on the second one. What do you mean by creating a formula for the minimum volume of hand sanitizer each day. What HL maths are you going to use?
@@MrFlynnIB it is just a formula to estimate minimum volume of hand sanitizer that should be used for a person for each day, i will be measuring the area of palm, and drop some sanitizer on until all part of hand were cover with sanitizer, from that , maybe i can try to find a formula for it? haha
@@manfredyong6543 Ya that sounds like you are on to something. I would say this idea is more interesting to me but the other one would be easier for you to make into an IA.
@@MrFlynnIB Hi Sir, sorry hehe so currently I am doing my IA but I got stuck in the midway planning my IA: Can a hand sanitiser bottle with a dropper be designed and what is the best size of it to be recommended in the usage of daily life to avoid wastage? For this actually, I am having problems in choosing which Maths HL Topic should I include in my exploration, my planning in doing this at first were basically 1. Finding differents area of palm ( both back and front ) for each people, and then I will take out some volume of hand sanitiser for them to rub on both sides of their hand, and finally i will get the average volume for hand sanitiser used for one particular area of the hand, and I will proceed it with the second person and so on, 2. After I get all the data, then I can get the average hand sanitiser for different sizes of hand, from that I am going to model my hand sanitiser But when I were discussing about it again with my friends, we find it more related to physics, thats why hahaha, because of the dropper and the pressure which will help it to be sucked out from the bottle, so we just think that, " how can it be maths ia if lots of physics in it later ", so I am confused a bit now, But I have think about a few topics, Differentiation, Integration and Progression maybe? Seems I will be using different sizes and area of hand, I found out that lots of research were saying about the average sizes of hand were seems like a pattern Like 11.5inch then 13 inch 14.5 inch , So if I were going to use progression for the modelling,do you think its okay? Or maybe you have other suggestions
Hi, thanks for the video. I am interested in architecture, especially in cool modern buildings. Do you think calculating the surface area of the Museum of the Future in Dubai would be a good IA focus for an AA HL student?
Hi, love the video. I have a question. My teacher in school says that for hl students the math used must be only in the HL course and the not the SL one to get a 4,5,6 on criterion E. Is this true??
Kind of but not 4. Just 5,6. To get a 5, you must demonstrate 'sophistication'. And 'sophistication' according to the guide means 'commensurate with the HL course or, if found in the SL course it is beyond what an SL student could reasonably be expected to do.' I have a video on each criteria so I explain more there if you want to watch.
hello is doing a math IA on solids of revolution (seeing how many jellybeans can fit inside a coke bottle using this concept) ok for SL math? Does it cover enough course content as there is a lot of integration involved. I am planning to graph the coke bottle and jellybean to find the volumes and seeing how many jellybeans can fit inside.
Hello Sir, I am struggling with finding a suitable idea for my AI HL IA but I recently thought of doing something along the line of - using Voronoi diagrams to map out and calculate how many (minimal) Nuclear bombs it would take to completely destroy the whole surface of the planet. However, I am not sure how I would incorporate other types of higher-level maths into it or even if using Voronoi diagrams makes sense... Any suggestions? Thank you.
I like this idea. Nothing wrong with Voronoi diagrams for HL but you might want to go into more detail than an SL student might. Have you looked at graph theory? I think this is a good option for AI HL. I'm planning on this being my next IA video.
Hi Mr. Flynn, do you think I could do my IA on modeling a perfect squat technique? I am interested in lifting and want to find angles and speed needed to do a squat effectively. I am math AA SL so I do not know if this is complicated enough? I would use images to analyze the different angles and maybe graph a speed curve too.
It’s me again, I thought about the Idea more and think there is not enough of a clear aim when thinking about this question. Instead I thought about analyzing different values of golden cuts in hurricanes and how it effects it intensities. Do you think that would make more sense? It would have a statistics twist to it as well.
Hi Sir, I've recently changed my IA idea (AAHL). I'm planning on doing a modelling IA, where firstly I do an experiment (where I collect some quick data to help the personal engagement section), then plot the data and attempt to model it with various attempts and reflections (good for crit d). Despite this I am having lots of trouble finding an experiment which can do this. An example I found online was the "microwave popcorn" one. Is there any experiment ideas or model ideas you may know work well for this? Fyi, my teacher is quite difficult to reach, therefore I am contacting you. I greatly appreciate your help.
Really this is the bit that you need to do yourself. Sounds like you have a decent plan but find something that you care about. For example, I am interested in running, so I might collect running data and model that to see how to improve. If you are interested in tv shows, you could find data from say netflix and create a survey to give to your year group and look for interesting patterns. There are endless options but pick something that interests you.
Hello Mr. Flynn, as an AA SL student, I was thinking of taking the Sochi F1 track and finding the length of it (y=mx+b for straights, length of an arc for hairpins, and integration for other corners). However, I'm not really confident with this topic. I was wondering if you think this topic is doable?
It is difficult for sure. Maybe more of a HL topic. The length of an arc (not arc of a circle) formula isn't even in the HL course. It is doable but difficult. Why not just focus on a part of the track like a particularly difficult corner and find the length of different racing lines to see which is the shortest?
Hey Sir, I was planning on calculating the volume of a modern, unique shaped building near my school. But I am not sure about the math I am going to use may you please suggest me something?
Yes, I think I mention one in my next video (part 8). Modelling the shots of different clubs and comparing. You can get the derivative to find the angle or get the area under the curve to see which shot clears the most space. Also lots of statistics you could use.
Hello Mr. Flynn. I'm in SL AA and I'm doing my ia about calculating moon's instant velocity using derivates. I've already done that, and it didn't come up with a coherent result. The thing is I need to do something more, and I thought about graph the ellipse, but I'm not sure if it's fine. Thank you!
Hi Agustina. Firstly what do you mean when you say 'it didn't come up with a coherent result'. This sounds like an interesting idea. I would not suggest adding more if it is already incoherent. I would say either go back and complete your original idea or focus on a different aim. What do you mean when you say graph the ellipse? What would be your aim?
@@MrFlynnIB Hi Mr. Flynn. How are you? I've been working and I think that what I did wrong was using few points to come up with a function to derivate. So now I will try to find more points (by points I mean distances from the Earth to the moon). In this way I hope I can come up with a better function so I can derivate it and get the moon's intant velocity. Then what I though is that I could graph that orbit using the concept of the ellipse. I would like to know your opinion. Thanks!
@@agustinaesponda31 Graphing the ellipse is interesting. I'm not entirely sure how you plan to get the instant velocity of the moon. If your function models the distance of the moon from the earth against time, then the derivative will give you the velocity of the moon relative to the earth. Is that what you want to find?
Hi Mr. Flynn! I had a question about the example you showed for Quadratics, the table tennis serve. I was wondering what had they done after they got the Gradients or Angles of the quadratic, like what did that information mean to the exploration? I'm doing something similar with Badminton shots and I'm going to find maximums and areas under the curve but I wanted to find the initial angle of 2 different serves. However, both services start at a different height and the angles aren't really comparable anymore right?
So he was comparing his backhand serve to his forehand serve. He wanted to know why his backhand was better. Angles are important in table tennis. Why are the angles not comparable? I think it is useful to compare and talk about why one is better than the other.
@@MrFlynnIB I think that because the serves in badminton start from different heights, and let's say 45 degrees is good for one serve, it may not even pass the net in the other serve. That's why I'm worried I cannot make a final statement like, lower the angle the better or something along those lines. Should I just acknowledge the height differences and just determine which one is the best?
@@beaudubois you don't need to make that final statement. You could have the best angle for each type of serve. There is lots to work with and this type of discussion can really help with your reflection and also demonstrate mathematical understanding.
@@beaudubois No to find the angle, you should get the derivative of the function at whatever point. That will give you the tan of the angle. Inverse tan will get you the angle.
Hello sir, I am doing AA HL and I want to do something related to the volume of revolution. Do you think it's a good idea to find out the volume of a submarine to find out the time it will need to be filled with water if there is a hole in it? Maybe I could also do something related to Buoyant forces... Or do you think it wouldn't be as focused/too much physics involved? Or shall I just keep it simple and focus on a vase, and use both Shell's method and disk method and compare them with the actual volume? The reason behind it could be that I always ship stuff from other countries and the cost is counted per m^3 and I want to know how much it could cost for me to ship it? So sorry for my stupid random questions, and thank you for posting the videos!
I definitely prefer the submarine idea to the vase. Why would you do a vase? I like the idea of how long it will take for the submarine to sink. You could also apply this to a boat. You could even see how long it would take for the boat to sink if you had a bucket and were bailing out the water. Ya the shipping rationale is a good one. I assume you aren't shipping on a submarine though?
@@MrFlynnIB thank you so much sir, but I don't think my shipping rationale would fit for the submarine... it was mainly for the vase, do you have any idea of how I can link it? Also sir do you have any idea of what math and method I should use to calculate them if I was to do the sinking question?
@@MrFlynnIB Also Sir, what do you think about SIR models? My math teacher really like it but people are saying it’s overused and you can’t score well on it. Do you think the math is enough AA HL? Do you have any suggestions on how I should approach it? Thank so so much for your time!!
@@MrFlynnIB Hello Sir I really wanted to use your idea of calculating the volume of the ship and finding how long it will take for the ship to sink. Could you please give me a guideline to calculate this time?
@@이강준-q3b You need to find out how big the hole in the ship is (if there is a hole). And hence how fast the ship is taking on water. Then you would need to find out what percentage of the volume needs to be filled with water for the ship to sink. Then find the time to get to this percentage. Something like that?
Hi Mr. Fynn my IA is on "How did Tommy Thompson use the Bayes Theorem to search for the ship of SS Central America? " Do you think this is a good enough topic or should i select something more practical and personal.

Hi Mr. Flynn, I'm doing my math IA in the birthday paradox but it doesn't have enough math nor personal engagement. I'm thinking of making this a bit more relevant to what I learned in Bio class: How many people need to be in a room such that there is a greater than 50% chance that 2 people share the same genetic disease. I'm still worried that there won't be enough Math, do you have any suggestion or would you advise me to change my topic?
@@MrFlynnIB I think so too but my Math teacher is not acknowledging this issue with the birthday paradox, and he didn't inform me about this topic being overused prior to the first draft. Can you suggest some ideas that I can do? I'm in Math AA SL. I've tried asking to change my IA topic to modeling an object but many other students are doing this already. Would truly appreciate your response! :)

Hi sir, I am an AI HL student. I was thinking of doing a IA on digital image processing. Basically using the Statical methods and Fourier transform to add filters and make it a proper likable image. Is that fine?
Fourier transform IAs always worry me as it is difficult to explain what you are doing in a way that a peer could understand. Having said that, it sounds like a nice idea and could be good. Just make sure you really understand what you are doing and explain it well.
Dear Mr Flynn, I was asked to get into contact with you about IA. I'm in AA HL and have done an IA about volumes of revolution for a vase, where I used the shell and disk method, and I got a nice result. I am now at 12 pages. My Maths teacher wanted an extension of me finding the volume of the Tycho Brahe planetarium using double integrals. I like the idea, but my classmate "Lucas Bækgaard" said that Mr Flynn said the IA must be as concise as possible. Should I stop at what I have?
That's a tricky one. Firstly make sure you listen to your teacher as they are going to mark it. Lukas is correct that it must be concise but that doesn't mean you can't do an extension. I think it could be nice to find the volume of the Tycho Brahe planetarium but your IA needs to flow nicely so if your aim is to find the volume of a vase and then you do that in detail and then out of nowhere you are finding the volume of a planetarium, it doesn't look good. Perhaps you could incorporate it into your aim or else in your conclusion and as part of your reflection you could mention it as a possible extension. You could do the math very quickly without going into as much detail. Let me know if that helps.
@@MrFlynnIB I understand. So I made an extension from the vase saying that I will find the volume of the planetarium, but instead of using random methods such as double and triple integrals, I can use the shell method like before to keep it concise, and prove it with the simple geometric formula of pi*r^2*h. I will implement this in the aim saying, "I want to find the volume of the vase, and then if it seems reasonable, find the volume of the planetarium". How does this sound?
Hello Mr. Flynn. My IA is similar to the one with the population of India and China with logistic function. Do you maybe have an example of it or some recommendations for the math part for AI Sl? Thank you in advance :)
On my website, I have videos where I go through complete IAs. Not on UA-cam however. For AI SL, it is probably enough just to create the models and then find where they are equal. I like to start with a linear model, reflect, then try exponential, reflect and then finish with a logistic which hopefully is the best. And reflect some more.
Hello, Mr. Flynn, I am thinking of doing something with sinusoidal modeling and weather but I’m in AA HL. I think my aim would be great, but would this be enough maths for HL? Thank you!
It can be if you go into more depth than what an SL student would do. Also remember even if you only do what an SL student would do, you can still get 4/6 for criterion E which makes 18/20 possible.
I haven't come across many good music IAs. They are difficult to do well. I had a very good one a few years ago that compared the graphs of note combinations that sound good v ones that don't. I also have a great one this year that looks at the relationship between the volume of liquid in a glass and the note produced by touching the edge of the glass.
Hi Mr Flynn, I was just wondering if you could help me with my IA in relation to architecture. ( I do AA SL btw), I don't really know what maths to use but I've heard people recommend Euclidean Geometry, area and Voronoi diagrams. I came up with one idea but I don't know if it would be too complicated and I don't know what exact maths to use. It would be along the lines of 'analysing an existing building and redesigning it on sketch up' I could re-evaluate how the roof or angles/volume could be altered to make it more sustainable for the environment it is in (e.g. heat retention, snow/rainfall and pressure distribution.) I was also interested in using Voronoi diagrams for urban planning and calculating where to build a facility. Thank you so much!
Hi Isabella. I like the building idea. Be careful using just angles and basic area and volume as the maths might be too simple. You could use integration to find areas (like the school example in my video). That might be better. Voronoi diagrams is a good topic but a separate one. Don't do both of these together. I have 2 videos on UA-cam on Voronoi diagrams.
@@MrFlynnIB Thanks, Mr Flynn. She said the Voronoi diagram would be too complex for my level. I really want to do something related to coffee and latte art as I'm training to become a barista. She said I could do it if i come up with an idea quickly as my draft is due in 3 weeks. I don't really know what maths to use. I was thinking of how pouring heights and angles affect the latte art but if that's too hard to show maybe something to do with brewing time etc. I'm really not sure and any help would be greatly appreciated.
@@bellafrancess Voronoi diagrams is considered one of the easier topics in the course so I wouldn't rule it out. Do some research and try to convince your teacher. You could even relate it to coffee. Where is the best place to build a new Starbucks? Otherwise, I really like the idea of modelling the temperature of coffee and finding how long to wait before drinking it.
Hi Mariam. Pure math is basically math for math sake without looking at any real life application. An example might be 'why is Euler's identity considered the most beautiful equation in the world?'. A modelling IA is generally when you model something in real life using mathematics. Considering the criteria for the IA, I don't recommend pure math IAs unless you have a great idea and really know what you are doing.
Hi sir. Do you perhaps have a topic in mind,sir? I'm stuck and now I have 3 more days to finalise my title for MAA SL IA. I wanted to do something on the golden ratio but its too overrated and has a high possibility of plagiarism. It would be nice to have some ideas. I am truly desperate. Thank you
@@MrFlynnIBI saw your video about the sinusoidal modeling temperature. I plan on doing something related to that and finding the best temperature to dry clothes, finding the polynomial best fit, and from the best-fit equation, I can model the trigonometric function for my graph, and determine when the temperature is the highest. But other than that I do not have other maths ideas. Maybe finding the probability of rainy days? But I am not sure. Do you have any suggestions? Would really appreciate it:)
@@MrFlynnIB I also have another idea of comparing the speed of writing, keyboard typing, and voice typing. To see which one is most efficient to use for exams. It is mostly statistical use and that worries me because my teacher wants more than 2 topics of maths in the research.. I plan on doing the probability of normal distribution also and finding a correlation coefficient between any 2 methods. For instance, does the speed of typing depend on how fast you write but I am still not that sure about it.
@@adrianabintikhalid133 Ya I like that. Or what time to put out the clothes to make sure they dry? You don't need the polynomial best fit. Just create the equation yourself using transformations and solve the equation to find the time at which to put out the clothes. You could do the probability of your clothes drying in time if you put it out at a random time. I wouldn't do the probability of rainy days as this is basically a different type of IA and would make yours not concise.
Hi Mr. Flynn, thank you for this video, it is a lifesaver.

It’s a good idea. I find the angle it enters the basket also interesting. I would make sure to use differentiation to find the angles. You might struggle to get more than 4 for criterion E if you only use quadratics. But 18/20 is not bad if you can get the rest. Watch my ‘Criterion E’ video to see what I mean about the mathematics.
@@MrFlynnIB I watched all your videos pertaining the IA and since I was thinking to make it more HL I can possibly use vectors to get the angle since SL do not take vectors in the AI course. I agree an 18 would be good.

I'm in HL AA and I was wondering if doing an IA that models geometry dash and the music that plays in the background would be enough HL math. I believe I'd calculate the curve that the square goes on with each jump and maybe graphing the changes in pitch to see during which pitch or shift a jump is necessary. I also had another idea but was not sure about the math that would go into it, the perfect teapot to produce laminar flow and prevent spillage when pouring. I'm sorry if this is an inconvenience
Hi Radia. Sorry I'm not familiar with geometry dash but it sounds interesting. The tea pot idea sounds good but I would ask what is your plan?
Hi Mr Flynn, thanks so much for this video, it really cleared a lot of things up. Coincidentally, my idea for my IA was F1, do you have any other suggestions for more specific topics within F1?
I like the thought of modelling the velocity against time of two different cars passing through a specific turn and then compare. You can use calculus to find max and min velocity along with acceleration. Talk about which car is better. Which driver is better. That's just one idea. Have a think of a few more and I will let you know if they might work .
@@MegaMelonDog Yes I like that idea too.
Hey, i'm dong an IA on gini coefficient, what complex math should I use to find the area of the curve (the equation isn't known to us)

I need to find a topic for my math ia, i have ai hl, and i was thinking maybe i could compare a bowling strike in real life compared to in wii sports and compare them using quadratic modelling, but i don’t think it will reach hl, could i possibly include vectors in the context of the position of the bowling ball and the pins?
Hi Mr Flynn, thank you for this video. I found it so helpful and useful! However, i have a question. I am planning on finding the volume of revolution or maybe using ellipse modelling for a rugby ball but currently I have no idea on what to relate it to. Do you think if i relate it with the spinning of the ball would be a good idea? or do you have any other better idea regarding the volume of revolution or ellipse modelling?
Volume of an ellipsoid is good. Really it's you that needs to come up with a good reason for doing it. A common idea might be to see which is bigger the volume of a football or rugby ball. You might want to see is the ratio between a size 5 and size 4 football the same as the ratio between a size 5 and size 4 rugby ball. Let me know what you come up with.
Hello Mr Flynn, thank you for the video! i really needed it and i do find it useful. But, to be honest, I still havent gotten any idea for my ia math topic. Every video that I watched mention about finding a topic based on my interest, but I still couldnt find one until now. I dont think that all of my interests have something to do with math, so I am having a very hard time to think of a topic. I really need guidance, Mr Flynn.
What are your interests? Remember it doesn't have to be your hobby or passion. For example we are all interested in the corona virus at the moment so perfectly reasonable for anyone to do an IA on that. No doubt there will be a lot IA's on covid this year. Also a really good IA I had which you might have seen was finding the area of the school. I wouldn't say that my student was passionately interested in the area of the school but he did genuinely wonder 'how big is the wall' and then became very interested in the mathematics involved rather than the final answer.
@@MrFlynnIB Mr Flynn, Im back! I already have an idea in mind but im thinking of asking for your opinion first. Im thinking of modelling fruit (one of these options) like watermelon, coconut, lemon, or maybe banana using the ellipse equation. The aim for this is to find the volume of its flesh, the number of people that can be served to, the amount of juice that can be produced and served from the fruit. what do you think about this idea, mr flynn?

Hi Mr. Flynn. Thank you for all your guidance regarding the IA. I’m a math AI SL student and you said that correlations IA’s don’t score as high as other IA’s. I’m doing mine in correlation, do you have any ideas or tips which could help me further increase my grade even while doing a correlation IA ?
Hi Ayesha. The main reason students don't score well with correlation IAs is that they usually sub numbers into a formula without really showing understanding. For sure it is possible to score well but you have to show the reader that you have a really good understanding of what you are doing. Explain the formula for r, where it comes from and why it works.
Thank you Mr. Flynn, I could certainly do that. If I am correlating two factors, what other tips would you suggest to score a high mark ?. Should I use a chi square test on the data or fo you have any other perspectives would you recommend. I am in quite a pickle as I regret choosing this topic but I am trying to do it to the best of my ability.

Hi Mr Flynn, I just want to say I appreciate a lot putting the effort to help us get through the IA. I’m exactly the student that has jumped right into the correlation between life expectancy and GDP per capita. However, I’m doing it with education and how some other social factors may also influence its correlation.
I was never satisfied with the idea and never saw a future with it. I’m still lost and not sure what to do, but I now with the right topic I could do my IA in a very short period of time. Hence, do you have any suggestions? Should I change my topic (Because I’m aiming for a high 6 or 7)? Perhaps with optimization? (I’m math HL A&A by the way).
I would probably suggest you change if you are HL and looking for a 6 or 7. Have you watched part 7 and and part 8. A lot of ideas there. Anything that interests you?
@Mr. Flynn IB Wow, thank you so much for your early reply. I have watched part 7 and part 8, I was really interested in doing something with the Voronoi diagrams (some kind of situation of placing in the most efficient places some health care centers that would prevent the risk of patients dying during their way to the hospital and perhaps do some probability as well).
I also had a meeting with my math teacher today and told me to stick with the same topic, if I explain step by step the linear regression and coefficient formula, add all kinds of tests (e.g. T-test, Chi-square test), and go then more in depth with other kinds of factors (more into comparing their functions in relation to life expectancy) I should be fine to get a 6 or 7. However, I'm not sure if this is really the case, what you do think?
@@manve5652 You can get a 6 or 7 with any topic in the course if it is done well enough. Life expectancy v GDP is probably the most done topic of all time which is why I'm not a big fan. It's up to you. If you genuinely interested in it, go for it.

Dear Mr Flynn, actually I have confusion in choosing which MAA HL IA topic that I should choose, at first I thought of having modelling for hand sanitizer with syringe inside ( the syringe is used to take out the volume of hand sanitizer to be used for each day) as my IA project, the second one is by making formula of minimum volume of hand sanitizer used for each day, which one do you think is more appropriate, or should i rethink about both of it again?
Interesting. I like both but I'm not clear on the second one. What do you mean by creating a formula for the minimum volume of hand sanitizer each day. What HL maths are you going to use?
@@MrFlynnIB it is just a formula to estimate minimum volume of hand sanitizer that should be used for a person for each day, i will be measuring the area of palm, and drop some sanitizer on until all part of hand were cover with sanitizer, from that , maybe i can try to find a formula for it? haha
@@manfredyong6543 Ya that sounds like you are on to something. I would say this idea is more interesting to me but the other one would be easier for you to make into an IA.
@@MrFlynnIB Hi Sir, sorry hehe so currently I am doing my IA but I got stuck in the midway planning my IA:
Can a hand sanitiser bottle with a dropper be designed and what is the best size of it to be recommended in the usage of daily life to avoid wastage?
For this actually, I am having problems in choosing which Maths HL Topic should I include in my exploration, my planning in doing this at first were basically
1. Finding differents area of palm ( both back and front ) for each people, and then I will take out some volume of hand sanitiser for them to rub on both sides of their hand, and finally i will get the average volume for hand sanitiser used for one particular area of the hand, and I will proceed it with the second person and so on,
2. After I get all the data, then I can get the average hand sanitiser for different sizes of hand, from that I am going to model my hand sanitiser
But when I were discussing about it again with my friends, we find it more related to physics, thats why hahaha, because of the dropper and the pressure which will help it to be sucked out from the bottle, so we just think that, " how can it be maths ia if lots of physics in it later ", so I am confused a bit now,
But I have think about a few topics,
Differentiation, Integration and Progression maybe? Seems I will be using different sizes and area of hand, I found out that lots of research were saying about the average sizes of hand were seems like a pattern
Like 11.5inch then 13 inch 14.5 inch ,
So if I were going to use progression for the modelling,do you think its okay? Or maybe you have other suggestions
@@manfredyong6543 I think if you focus on area and volume and modelling then it is fine.
Hi, thanks for the video. I am interested in architecture, especially in cool modern buildings. Do you think calculating the surface area of the Museum of the Future in Dubai would be a good IA focus for an AA HL student?
Hi, love the video. I have a question. My teacher in school says that for hl students the math used must be only in the HL course and the not the SL one to get a 4,5,6 on criterion E. Is this true??
Kind of but not 4. Just 5,6. To get a 5, you must demonstrate 'sophistication'. And 'sophistication' according to the guide means 'commensurate with the HL course or, if found in the SL course it is beyond what an SL student could reasonably be expected to do.' I have a video on each criteria so I explain more there if you want to watch.

Hello Sir, I am struggling with finding a suitable idea for my AI HL IA but I recently thought of doing something along the line of - using Voronoi diagrams to map out and calculate how many (minimal) Nuclear bombs it would take to completely destroy the whole surface of the planet. However, I am not sure how I would incorporate other types of higher-level maths into it or even if using Voronoi diagrams makes sense... Any suggestions? Thank you.
I like this idea. Nothing wrong with Voronoi diagrams for HL but you might want to go into more detail than an SL student might. Have you looked at graph theory? I think this is a good option for AI HL. I'm planning on this being my next IA video.

Sounds like a maybe. Could you add in some optimisation to find the best angle?
It’s me again, I thought about the Idea more and think there is not enough of a clear aim when thinking about this question. Instead I thought about analyzing different values of golden cuts in hurricanes and how it effects it intensities. Do you think that would make more sense?

Hi Sir, I've recently changed my IA idea (AAHL). I'm planning on doing a modelling IA, where firstly I do an experiment (where I collect some quick data to help the personal engagement section), then plot the data and attempt to model it with various attempts and reflections (good for crit d). Despite this I am having lots of trouble finding an experiment which can do this. An example I found online was the "microwave popcorn" one. Is there any experiment ideas or model ideas you may know work well for this?
Fyi, my teacher is quite difficult to reach, therefore I am contacting you. I greatly appreciate your help.
Really this is the bit that you need to do yourself. Sounds like you have a decent plan but find something that you care about. For example, I am interested in running, so I might collect running data and model that to see how to improve. If you are interested in tv shows, you could find data from say netflix and create a survey to give to your year group and look for interesting patterns. There are endless options but pick something that interests you.
Hello Mr. Flynn, as an AA SL student, I was thinking of taking the Sochi F1 track and finding the length of it (y=mx+b for straights, length of an arc for hairpins, and integration for other corners). However, I'm not really confident with this topic. I was wondering if you think this topic is doable?
It is difficult for sure. Maybe more of a HL topic. The length of an arc (not arc of a circle) formula isn't even in the HL course. It is doable but difficult. Why not just focus on a part of the track like a particularly difficult corner and find the length of different racing lines to see which is the shortest?

The thing is I need to do something more, and I thought about graph the ellipse, but I'm not sure if it's fine. Thank you!
Hi Agustina. Firstly what do you mean when you say 'it didn't come up with a coherent result'. This sounds like an interesting idea. I would not suggest adding more if it is already incoherent. I would say either go back and complete your original idea or focus on a different aim. What do you mean when you say graph the ellipse? What would be your aim?
@@MrFlynnIB Hi Mr. Flynn. How are you? I've been working and I think that what I did wrong was using few points to come up with a function to derivate. So now I will try to find more points (by points I mean distances from the Earth to the moon). In this way I hope I can come up with a better function so I can derivate it and get the moon's intant velocity. Then what I though is that I could graph that orbit using the concept of the ellipse. I would like to know your opinion. Thanks!
@@agustinaesponda31 Graphing the ellipse is interesting. I'm not entirely sure how you plan to get the instant velocity of the moon.

Hi Mr. Flynn! I had a question about the example you showed for Quadratics, the table tennis serve. I was wondering what had they done after they got the Gradients or Angles of the quadratic, like what did that information mean to the exploration?
I'm doing something similar with Badminton shots and I'm going to find maximums and areas under the curve but I wanted to find the initial angle of 2 different serves. However, both services start at a different height and the angles aren't really comparable anymore right?
So he was comparing his backhand serve to his forehand serve. He wanted to know why his backhand was better. Angles are important in table tennis. Why are the angles not comparable? I think it is useful to compare and talk about why one is better than the other.
@@MrFlynnIB I think that because the serves in badminton start from different heights, and let's say 45 degrees is good for one serve, it may not even pass the net in the other serve. That's why I'm worried I cannot make a final statement like, lower the angle the better or something along those lines. Should I just acknowledge the height differences and just determine which one is the best?
@@beaudubois you don't need to make that final statement. You could have the best angle for each type of serve. There is lots to work with and this type of discussion can really help with your reflection and also demonstrate mathematical understanding.
@@MrFlynnIB All right, thank you so much! I appreciate it. Also, to find that angle I will just be doing Trig Ratios with a tangent, right?
@@beaudubois No to find the angle, you should get the derivative of the function at whatever point. That will give you the tan of the angle. Inverse tan will get you the angle.

Hello my teacher, i enjoy math AA
Dear Mr Flynn, I was asked to get into contact with you about IA. I'm in AA HL and have done an IA about volumes of revolution for a vase, where I used the shell and disk method, and I got a nice result. I am now at 12 pages. My Maths teacher wanted an extension of me finding the volume of the Tycho Brahe planetarium using double integrals. I like the idea, but my classmate "Lucas Bækgaard" said that Mr Flynn said the IA must be as concise as possible. Should I stop at what I have?
That's a tricky one. Firstly make sure you listen to your teacher as they are going to mark it. Lukas is correct that it must be concise but that doesn't mean you can't do an extension. I think it could be nice to find the volume of the Tycho Brahe planetarium but your IA needs to flow nicely so if your aim is to find the volume of a vase and then you do that in detail and then out of nowhere you are finding the volume of a planetarium, it doesn't look good. Perhaps you could incorporate it into your aim or else in your conclusion and as part of your reflection you could mention it as a possible extension. You could do the math very quickly without going into as much detail. Let me know if that helps.
@@MrFlynnIB Do you have an email where I could send you my IA and see if I should add the planetarium part in?
Kindest Regards, Anas
@@Anas0312780 Sorry Anas I don't take IAs to read. As you can imagine, I would get a lot.
@@MrFlynnIB I understand. So I made an extension from the vase saying that I will find the volume of the planetarium, but instead of using random methods such as double and triple integrals, I can use the shell method like before to keep it concise, and prove it with the simple geometric formula of pi*r^2*h. I will implement this in the aim saying, "I want to find the volume of the vase, and then if it seems reasonable, find the volume of the planetarium". How does this sound?
Hello Mr. Flynn. My IA is similar to the one with the population of India and China with logistic function. Do you maybe have an example of it or some recommendations for the math part for AI Sl? Thank you in advance :)
On my website, I have videos where I go through complete IAs. Not on UA-cam however. For AI SL, it is probably enough just to create the models and then find where they are equal. I like to start with a linear model, reflect, then try exponential, reflect and then finish with a logistic which hopefully is the best. And reflect some more.
Hello, Mr. Flynn, I am thinking of doing something with sinusoidal modeling and weather but I’m in AA HL. I think my aim would be great, but would this be enough maths for HL? Thank you!

Hi Mr Flynn, I was just wondering if you could help me with my IA in relation to architecture. ( I do AA SL btw), I don't really know what maths to use but I've heard people recommend Euclidean Geometry, area and Voronoi diagrams. I came up with one idea but I don't know if it would be too complicated and I don't know what exact maths to use. It would be along the lines of 'analysing an existing building and redesigning it on sketch up' I could re-evaluate how the roof or angles/volume could be altered to make it more sustainable for the environment it is in (e.g. heat retention, snow/rainfall and pressure distribution.) I was also interested in using Voronoi diagrams for urban planning and calculating where to build a facility. Thank you so much!
Hi Isabella. I like the building idea. Be careful using just angles and basic area and volume as the maths might be too simple. You could use integration to find areas (like the school example in my video). That might be better. Voronoi diagrams is a good topic but a separate one. Don't do both of these together. I have 2 videos on UA-cam on Voronoi diagrams.

Hi Mariam. Pure math is basically math for math sake without looking at any real life application. An example might be 'why is Euler's identity considered the most beautiful equation in the world?'. A modelling IA is generally when you model something in real life using mathematics.

It is mostly statistical use and that worries me because my teacher wants more than 2 topics of maths in the research.. I plan on doing the probability of normal distribution also and finding a correlation coefficient between any 2 methods. For instance, does the speed of typing depend on how fast you write but I am still not that sure about it.
@@adrianabintikhalid133 Ya I like that. Or what time to put out the clothes to make sure they dry? You don't need the polynomial best fit. Just create the equation yourself using transformations and solve the equation to find the time at which to put out the clothes. You could do the probability of your clothes drying in time if you put it out at a random time. I wouldn't do the probability of rainy days as this is basically a different type of IA and would make yours not concise.
Mr Flynn you sound like Elon musk
he really does
Hi Mr. Flynn, thank you for this video, it is a lifesaver. Im doing my IA on angry birds, except im modelling the chicken bird that shoots an egg and goes flying, i worked out that the angle it goes flying is always the same, so i want to use projectile motion and kinematics for my model. Do you think this is a good idea?
Hi Lucas. Yes I like this (modelling the chicken bird) but what is your plan with projectile motion and kinematics? What is your aim? I don't see an easy way to use kinematics.
@@MrFlynnIB I am using tracker video analysis software to find gravitational acceleration and velocity when ability is used(velocity which i found out is always roughly the same) Then using trajectory equation for projectile motion.
@@MrFlynnIB the aim is to find the equation of the ability trajectory(of the chicken when it gets boosted) given the point you click the screen
@@lucasbaekgaard7596 Sounds good. You could maybe focus it more on when to activate the ability in order to hit a particular pig. Let me know how it goes.
@@MrFlynnIB I am unsure whether to use more than one example, or should I just show that my model works and then evaluate it? I am guessing the latter would be more concise, but i am not sure.
Mr. Flynn I am thinking about modelling my corner 3 shot in basketball and comparing it with different NBA specialist players like Stephen curry in order to find the optimal arch/angle that will result in the highest percentage of 3s made. I am AI HL would this be good enough. Your feedback is more than appreciated. Thank You!!
It’s a good idea. I find the angle it enters the basket also interesting. I would make sure to use differentiation to find the angles. You might struggle to get more than 4 for criterion E if you only use quadratics. But 18/20 is not bad if you can get the rest. Watch my ‘Criterion E’ video to see what I mean about the mathematics.
@@MrFlynnIB I watched all your videos pertaining the IA and since I was thinking to make it more HL I can possibly use vectors to get the angle since SL do not take vectors in the AI course. I agree an 18 would be good.
The only reason I even have an idea of what to do is because of your videos Mr. Flynn. Thank You sooo much for sharing all this information.
You could use vectors for any of the straight lines like your arm or hand position. That could work. I would use calculus for the curve though.
@@MrFlynnIB Okk thank you soooo much for the feedback and help you really helped me tremendously
