Thanks for this interesting video. I'm several years -- 54 to be exact -- out of high school, and I'm eager to relearn my math, just because it's worth knowing. There's something about the video I don't get. At 2:50, you say you're "shifting" y^2 + x^2 = r^2 to the right, yielding y^2 + (x-r)^2 = r^2. But for this shift to occur, doesn't (x-r)^2 have to substitute for x^2? I don't see how it does. Can you please help with this? I've been killing my brain on it.
That's precisely what she does at 2:50. She replaces x^2 in the original equation with (x - r)^2, in order to shift it to the right by r units. Since no other terms contain x, that's all the shifting you'd need to do.
Madam so quadratic equation is used for sporting purposes like to measure climbing, jumping what is it main purpose in daily life and technology (because not all are going to climb)
Yup. Algebra is used to find answers in everyday life. We use it when we talk. The word is means equals. Love is forgiveness and we have to forgive our abusers including the 1st grade math teacher who calls their students retarded. So balancing equations help come to the conclusion that everyday we can balance our time, food, sleep, company, etc. Forgiveness is not normal in capitalism but it is necessary for positive relationships. Sometimes we skip steps but we will have to correct it later. Also, not forgiving causes anger and we can die from a heart attack even if we eat healthily.
Okay, but most people don't climb under arched bridges. As fascinating and entertaining as this is, please, make me care about math in a day to day way. My wife loves teaching me math, and I just can't give a third of a fuck beyond hearing the sound of her voice. It doesn't help that I can't see well, I'm going blind. And assistance would be fantastic. Sorry for the language, I'm being flippant 😅 the video was great
I’m still confused on where this is important in any way. Why would I want to know how fast and how far he fell? I was trying to figure out on why this is important.
It's just a video applying math to an example. Most likely nobody watching this video cares about how far he climbed or fell. The point is to demonstrate the ways we use quadratic equations to explain real things. It's likely that if you actively refuse to see ways to apply equations to the real world, you'll never be able to use math to determine something you actually want to know.
Free fall is a special case where acceleration doesn't depend on the mass of the object, because everybody brought mass to the party. Both the force causing it, and the inertia brought mass to the party, and mass cancels out of the equation. On our planet, rounded to a nice round number, it's about 10 m/s^2. The global average is about 9.8 m/s^2. For acceleration in general, it does depend on the mass of the object, if the net force causing it is independent of mass.
A quadratic is a rectangle that is made of 1 or more squares but the y component increases faster or slower by a constant multiplied by the side of x. The lowest integer for the relationship is x^2 + 6x - 16 = 0 +16 +16 x^2 + 6x = 16 Complete the square by adding (1/2×b)^2 because x^2 ___________ 3x ____ I I I I I I I I I. I. I. I I__________I. I___I 3x. ___________ _____ I__________I. I 9 I I__ _I Add 9 x^2 + 6x + 9 = 25 First Inner Outer Last (x+3)^2 = 25 Square root both sides + or - (x+3) = 5 x + 3 = 5. Or. -(x) - 3 = 5 -x = 8 Answer is x = 2. Or. x = -8
How about we use the semi quadratic equation to solve the migrant border crisis this equation applies to population or quantities of anything or anyone
I can personally guarantee that the people that are climbing and the people that built this bridge didn't know the quadratic equation formula. So the question I have is; is learning this really useful or is it done mostly to try and impress?
You don't have idea how much matthematical calculations were used to hold that bridge and its own weight and weight above it surviving centuries earthquakes. It's all geometry
Why does anyone think that there is any human activity or experience that is not "in real life"? I think that a good philosophical argument cam be made that that phrase is "hollow".
Interesting comment. I used to hate back in high school they used to say "when you go out in the real world" and I used to laugh and say something akin to, well if this isn't the real world what is it? Oh the things I could've accomplished if I'd just realized that too was the "real world" and that I didn't need permission or two college degrees or a job to be great. You live and you learn. But if any kid happens to read this, if you wanna accomplish something, just start. You have all the time in the world. Don't wait.
I mean it isn’t. It’s just used in the wrong contexts and against the wrong subjects. But maths isn’t something we experience we do or experience so by your very own logic even that doesn’t fall under your paradigm.
@@misterbk1791 What are you saying isn't real life? Who is this "we" who don't experience mathematics? I don't recall stating a "paradigm" or mentioning one or calling one mine. In any case, I did not present a logic that I would call my "very own". On another note, what is your experience with carbon?
@@MrArtVeinI think what people mean, is "outside of something that is just an academic exercise, what it the application of this concept?" Whether it be application to a career, or application to a DIY project, or something else.
Real-life examples should be how it's taught. However, if you removed both of my hands, I can still count on my fingers how many times I have used this after getting my diploma. Yet taxes and insurance, something we deal with every year, is not taught and is mostly Greek to me. Ironically math is Greek, and I understand that much more
Not true. Not useless. For example. Take any simple archery mobile game. How do you find a trajectory of an arrow whilst it travels? Quadratic equation!
This is a great idea. Real world applications were sorely missing from my maths education
Nope they were paid anit enough to keep use educated 😂😂

Got this in my recommendation list, thanks to algo gods.
Please make more application videos like this.
Thanks for making this video it's great! will there be a sequel to the algebraic geometry video?
It's possible! Is there anything in particular you would want to see?
Sorry, too much background noise, bye, bye
@Madeline Brandt why are you substracting r from x???
You seem super exited to be sharing this knowledge!
beautiful explanation
Nice computation 🔥 btw the time assumed by video playback can also be affected by the fps it is shot and played on i think

Great video, Madeline! God bless you and thank you for helping humanity develop an understanding of mathematics!
This was excellent! Supreme.
This is fantastic! 😊 Would've paid so much more attention in school if I learned it like this.
How do you end up with 4r^2 in the quadratic formula? Would it not only be 2r^2 or am I missing something? Thanks!!
Also - would it not end up as r +\- root (r^2 - 2h^2)?
This is so much work. Congrats!
Amazing Madeline .... Are you Mathematician?
Really great.. awesome video
Wow ! Why can't I be like you? I wish they had this in my math class forty years ago.
So cool! Thank you.
Background music is too loud to understand anything.
Music was really annoying. 🤧

Good but could have done without the background music

ok why would someone in real life want to calculate something like this
thx
nice video, maybe this type of music is distracting a bit though :>

This is was amazing ❤

Hey i am from India well done teaching
Comment section is Wild😢 thank you for sharing your knowledge with us math dummies!
Yes he is right you are too much ...❤
Well Explained 👏.. But I do have doubt At, 1:45 acceleration depends upon Mass of the object , how did you say it as 10m/sec.
gravity
Acceleration Does Not Depends On the mass of the object .
It depends on the surface area which resists the air .
Free fall is a special case where acceleration doesn't depend on the mass of the object, because everybody brought mass to the party. Both the force causing it, and the inertia brought mass to the party, and mass cancels out of the equation. On our planet, rounded to a nice round number, it's about 10 m/s^2. The global average is about 9.8 m/s^2.
For acceleration in general, it does depend on the mass of the object, if the net force causing it is independent of mass.
Nothing better than girl next door explaining math! Just missed her telling us “let x equal ???”
“surly no one will pay attention to my elimination”
maths people:
What a lovely and helpful young lady.
Thanks a lot ❤️❤️❤️ mam
A quadratic is a rectangle that is made of 1 or more squares but the y component increases faster or slower by a constant multiplied by the side of x.
The lowest integer for the relationship is
x^2 + 6x - 16 = 0
+16 +16
x^2 + 6x = 16
Complete the square by adding (1/2×b)^2 because
x^2 ___________ 3x ____
I I I I
I I I I
I. I. I. I
I__________I. I___I
3x. ___________ _____
I__________I. I 9 I
I__ _I
Add 9
x^2 + 6x + 9 = 25
First Inner Outer Last
(x+3)^2 = 25
Square root both sides
+ or - (x+3) = 5
x + 3 = 5. Or. -(x) - 3 = 5
-x = 8
Answer is
x = 2. Or. x = -8

That's just physics, with math application
Wow
Simulation
Everyday, not every day.
For gord’d sakes ditch the unnecessary and intrusive music.
Not that bad, just needs to be lowered a bit lolll
It's nothing distracting if you are Einstein 😂😂
It’s like I asked her to give me a real world example of a quadratic after nothing her at a bar 😂😂😂
Are all mathematicians this annoying or are you guys just pretentious?
music? please no
:0
You are very beautiful ❤️
Thanks for spitting out useless informations. People like programmers will probably never use this formula.
People like you will never use these formulas, there not much call for quadratic equations and n the garbage collection business 😂
