I’ve watched this about 10 times so far ahaha always coming back to it to have a quick refresh, thanks so much sir! I’m so scared about failing and can’t seem to stop thinking about it and resitting. These two yrs have been so difficult 😭😭
Among all the A level maths UA-cam videos, your videos are the most useful and your teaching style is sooo structured and understandable. I love the fact that you explain the concept of equations or ideas, instead of just giving them to us and letting us memorise it. Thank you so much
You’re welcome! There’s also ones for mechanics and statistics too, plus tons of other stuff in my Bicen Maths Google Drive - check them out if you haven’t done already!
DUDE WHERE WAS THIS VIDEO WHEN I HAD TO GIVE MY FINAL EXAMS FOR 12TH GRADE. THAT LINK IN THE DESCRIPTION WHICH HAS ALL THE PDFS IS LITERALLY GOATED. THANK YOU SOO MUCH.
been watching your vids since my first applied tests last year, absolutely amazing mate - we do ocr but most of your stuff still applies, genuinely can’t thank you enough 👊 here’s to hopefully getting an a* come the summer 🙏
Great to hear this! Lots of similarities between all the exam boards, just a bit different at the last stage of exam style. You’re very welcome! Good luck with your studies 🍀
I've just finished a Maths and Physics degree at uni and I found myself relearning all of this during the video. It completely left my brain, which is either really telling of the education system or just my stupidity lol. I really wish I had this during my A-Levels though
Second derivative = 0 is not sufficient to show that it is a point of inflection, you must also show that there is a change in concavity ( gradient is +ve on both side of inflection point or gradient is -ve on both sides)
After most maths lessons I come to your channel and watch a video and then I understand it so well! Thank you so much, I can't believe this is all free!
I love to share my teaching with as many people as possible, as helping people to understand and love maths is what drives me! Thanks for the comment 👍🏼
Finally the video i was looking for, especially for the trig rules. Not a single other comprehensive list video with all the trig identities i needed. My go to yt channel exam solutions, even they don’t have all the trig identities in the form that is asked for in questions but instead just shows the proof for them so theres no condensed section with all the info at once.
Thank you for coming out with a great useful video that is good for last-minute revision. When I get a grade of A, you are one of the reasons. Once again thanks.
the trig integration ones that you list that you say arent in the formula book (secxtanx, cosec^2x, cosecxcotx), actually are, they are just in the differentiation section so you just have to look for the f'(x) column where they all are
Pleased that it’s useful! But I can confirm that what I said is correct - the right side is reflected onto the left - see this video around 3:00 for an explanation/confirmation. Good luck with your studies! ua-cam.com/video/7-wFBKG6f1w/v-deo.html
Hi Sir, I just wanted to ask about which topics are for AS and which are for the A-levels? Amazing content btw, these are rlly rlly helpful for my mocks tysm ur such a lifesaver oh goodness! We all recommended each other your channel on class and in the class groupchats too, so I hope your channel reaches more people that need help too:)
@@BicenMaths Sir, thank you so so much, you are so dedicated and I just wanted to say I feel like I aced that pure mock because of your videos - we had a completely iffy teacher all year and no one understood anything so everyone was so grateful when we found this channel - literal life support 🙌‼️I can't say the same about paper 2 though, it was like another monstrous paper 😭
I’m so pleased I could be of help - thanks for sharing this lovely comment with me. Wishing you (and your class!) the best of luck with your results 🤞🏼
Thank you! Yes, there will be a FS1 video like this coming soon - I am a bit behind with some of my recordings right now over the holidays, but I plan to get back to it soon!
doing some last minute revision, quick question but in what cases would you need to use the co-functions in the trig section? i've never come across them before, thank you for what you do
It’s super rare, but sometimes it’s worth knowing that cos50 is equivalent to sin40 for example. There’s been an equation previously where making this switch makes solving it really simple, and otherwise makes it nearly impossible!
Thank you so much for your videos you are amazing!! Also do we need to remember volumes of shapes? I remember a past paper question where we needed to know the volume of a sphere
Again, this is a very rare/niche area. It might be if a question had a sin40 and a cos50 somewhere in it, and you’re able to simplify the question by recognising you can replace sin40 with cos50!
its not preferred im guessing by the examiners who are mostly people who don't do maths so they might not understand it, better to follow by mark schemes and stuff imo
I appreciate this very very much but do you have a word processor copy, written in arial (i just find it easier to read)........if not it's perfectly fine.Thanks!
Yes, I’m working on this at the moment! I’ll be doing one for Core Pure 1 & 2, and a separate one for Further Mechanics 1. Pleased you found it useful! Check out the links in the description for the PDFs as well as other lessons.
Hi Mr Bicen, Hope you are well. I have started past papers, and I thought I understood the content but I keep getting really low grades such as D's or C's in the past papers. We have about a month now until the 1st pure paper, would you recommend that I keep going through all the papers and redoing the questions I get wrong, or go back over the textbook and reteach myself things. Thank you so much!!
Given what you've described, I would recommend a combination of those things - as you'll need to work on the exam question technique, as well as deepening your understand. I'd advise you to be quite focused about which parts you'll turn to in the textbook to deepen your understanding, as this should be informed by which questions you don't have the full understanding for! Sounds like you've got a good plan ahead of you - let me know if you need anything else.
Hi there, do you know if we would lose method marks if we use methods such as DI / tabular for integration by parts and coverup for partial fractions? I find they save alot of time and mistakes or should this be used as checking tool?
I have recently seen the DI method referred to in a mark scheme for IAL, so I know that it would be accepted there, but I haven't seen it yet in an Edexcel British A-Level paper! They're good methods for double checking, but I'm not sure of their validity without it being in an official mark scheme yet :)
Oh you are right! Take ln of both sides - you then get lny = xlna. Then you differentiate implicitly to get 1/y dy/dx = lna , then you get dy/dx=ylna, which is then dy/dx=lna a^x as y=a^x That’s it!
Hello dear thank you for excellent understand, I have 2 months before my As exam suggests me what how can I complete my books and question paper quickly.
Have a look at the other videos on my channel, as well as my Google Drive which is linked in the About section. Without knowing your starting point, it’s a bit difficult to recommend what to do - but using the textbook and doing lots of practice questions after the videos in my playlists will be a great starting point! Good luck!
Also, i would like to know whether you have such pdfs for chemistry and physics as well. (Dont worry if you dont, you have already given so much in this subject. This will really help me in the coming years) Thank you.
Yes, I did! I was so behind on comments, but I'm catching up now! You do need to know about the cofunctions, but it's very rare that they would come up - just be aware that if you see a sin25 that it is equivalent to cos65 for example - could offer up a shortcut/method to solve the question.
There's no specific proofs on here - but I have a couple of playlists on them: Year 1: ua-cam.com/play/PL0SSkmc4r_BZByta7XEwfF7Km96j94SxF.html Year 2: ua-cam.com/play/PL0SSkmc4r_Ba46qxQrdvRebWaSZf4XBJx.html
how similar is the content to cambridge international a levels? i'm studying the whole of maths and further maths in two months and this is the only good summary video / notes i've been able to find
The maths itself is all the same - but there are certain things in the international A-Level that aren't in the A-Level and vice versa, so you may need to add a couple of things into this video, and ignore one or two parts. I'm less familiar with the international paper, so can't say exactly which bits are in and out, I'm afraid!
is this just a part of the pure maths syllabus or can i use this and memorise and learn what was said because it looks like what was in the Cambridge syllabus pdf ps. im trying to figure out what i need to know exactly so i dont waste time as i am homeschooling and teaching myself and could really use any advice and help,thank you
The content for pure is the same for each exam board, but the exam tips I give are likely slightly different. So this is a good starting point! Let me know if there’s anything else you need. Good luck!
Yes the content is nearly totally the same - I can’t say which extra bits are here that shouldn’t be or vice versa (I don’t teach IAL so wouldn’t want to make a mistake in what I say!) but nothing on here would be “wrong” or “incorrect” for use in IAL. It’ll still be really useful!
why dont you recommend y = mx+c ? we have been taught to use y=mx+c for ages so why change and why would they teach us y = mx+c if we shouldn't use it?
It’s not that you shouldn’t use it, it just is less useful for the types of things you do in A-Level. For example, in GCSE you start off by investigating the y-intercept and gradient (so m and c are important) but at A-Level you become just as interested in where it crosses the x-axis, as well as other properties like where it intersects other types of graphs, where it doesn’t really need to be in the y=mx+c form to be able to use it. If you go for y=mx+c you have to solve it first to find c, then do other things like intersections etc. But with this formula you can immediately go to find those things without the additional work of finding c. If you’re happy with what you’re doing, don’t change it, but I always ask my students to trust me and go with the new form! Hope my explanation makes sense 👍🏼

Reminder to anyone looking through comments, you can learn to derive quite a few of these as backup for if you forget them in the exam.
Second derivative = 0 is not sufficient to show that it is a point of inflection, you must also show that there is a change in concavity ( gradient is +ve on both side of inflection point or gradient is -ve on both sides)

Hey sir at 31:42 how did you divide (x+1)/(x-1) into x^2/(x+1)
Love ittt
I do A level AQA maths. Does it have the exact same content ? Idk if I should watch these or not since this is Edexcel
The content is pretty much the same as far as I know - worth comparing to your textbook contents page though! All methods/formulae will be the same 👍🏼
Can this be used for IAL Edexcel ?
Thank you,
Yes the content is nearly totally the same - I can’t say which extra bits are here that shouldn’t be or vice versa (I don’t teach IAL so wouldn’t want to make a mistake in what I say!) but nothing on here would be “wrong” or “incorrect” for use in IAL. It’ll still be really useful!
why dont you recommend y = mx+c ? we have been taught to use y=mx+c for ages so why change and why would they teach us y = mx+c if we shouldn't use it?
It’s not that you shouldn’t use it, it just is less useful for the types of things you do in A-Level. For example, in GCSE you start off by investigating the y-intercept and gradient (so m and c are important) but at A-Level you become just as interested in where it crosses the x-axis, as well as other properties like where it intersects other types of graphs, where it doesn’t really need to be in the y=mx+c form to be able to use it.
If you go for y=mx+c you have to solve it first to find c, then do other things like intersections etc. But with this formula you can immediately go to find those things without the additional work of finding c. If you’re happy with what you’re doing, don’t change it, but I always ask my students to trust me and go with the new form!
Hope my explanation makes sense 👍🏼
Hi you forgot about exponential and logs and their models
Personally don’t think these models require anything extra to memorise - it’s just taking logs and comparing coefficients of the straight line graphs!
What's wrong with y = mx + c?
I’ve answered this in another comment!
22:00
Can I use these Everything you need to know videos even if I'm doing AQA Maths?
Yes, for pure it is nearly exactly the same!
