@MathVisualProofs WHAT wouldn't you agree I don't SEE ANYONE thinking of this substitution,no matter how smart theybare..wouldn't you agree? It's random or contrived and out of nowhere..Hope to hear from you.
Yes. I have that version in the works. If you check my channel you will see how many diagrams get repurposed for different results. This one shows up a few times. 😀
@@MathVisualProofs Thats the coolest thing about math. So many seemingly unrelated things just keep unexpectedly tying together in weird and magical ways.

@@leif1075Math, at it's core, is a tool used to examine the world in a more easily digestible way.

Interesting video. Previously I've seen Weierstrass substitution explained using the inscribed angle (x/2) versus the central angle (x) on a unit circle.
A:= (x,y,n) -> [[x,y], [-y, x]]^n B:=[1,0] B.A(1,z,2)=[1-z^2, 2*z] C:=(x,y,n) -> (x+i*y)^n C(1,z,2) = 1-z^2+i*2*z I call A the rotation matrix. Everyone tells me I'm wrong. I'm ok with being wrong. It is rotating by the angle [x, y] forms with [1,0]. The length is sqrt(x^2+y^2)^n. There is an ellipse that has a similar algebra. Both algebras are used in Mandelbrot Sets. I suppose it can also be called a translation matrix.
Para empezar, hacer Sustitución Trigonométrica x = sen t. Luego la Sustitución Trigonométrica Universal Otro método es usar la Sustitución Inversa haciendo t = 1 / (2 - x)
Hah here in India you should this vido to high school student and he will first be doing the laughter on you because then he will solve this in the next minutes because he was taught this technique when born. Ha
Very good visualization of a very elegant mathematical technique!
Glad you liked it! Thanks!

I learned about this substitution recently but this really explains the why! Thank you for your videos :)
Glad it was helpful!
What's insane about this is that this is also virtually identical to how you can prove the Sum/Difference Formulas for Sine and Cosine.

Alt method: multiply divide by (1-(sinx+cosx))

I've been trying to memorise the identities for a while and now I can derive them reasonably quickly, that's so helpful!
Glad it helps!
Bro that's amazing fr❤
Thanks!
Visual proof helps alot to understand it ,Thanks!
😀👍
HOOOOOLYYYYY, this is aweeeesome, very nice job, now i understand it well
Glad it helped!
Nice!
👍😀
Example is any linear combination of sines and cosines can be integrated like this
Amazing techniq
😀👍
Amazing 🔥
👍😀
Great visualization 😮
Thank you! Glad you liked it
awesome! thanks!
😀👍
KEEP DOIN ya thang I WATCH ALL ya videos ! Thanks for Visuals 😊
Thanks for your support :)
A:= (x,y,n) -> [[x,y], [-y, x]]^n
B:=[1,0]
B.A(1,z,2)=[1-z^2, 2*z]
C:=(x,y,n) -> (x+i*y)^n
C(1,z,2) = 1-z^2+i*2*z

if you scale the sides by z, won't the sides become lerger as ooposed to smaller? could you pls explain this to me
I am wondering the same thing
why can't you solve by multiplying both sides 1 + sinx - cosx
you could try doing the intergrale of dx/((2-x)(1-x^2)^1/2) please

Ok ...
Die Kunst!
