excellent video, but it would be better if there is a nicer font
It's sad that math isn't being taught like this everywhere
Sir make more videos about differential
Beautiful proof, thank you very much
Requires payment to download the video, wtf
More like… think once every three months. Got’em
I never understood that way before….thanks a lot , from Brazil 🙏
Ted-Ed has used your double pendulum video without giving you credits in their turbulence video. https://youtu.be/S3i6tJ4XNqA at 1:47 and 5:14.
This video made me want to cry, it’s so eligantly beautiful. It makes me see why so many have pursued mathematics with the passion that they have. It truly is the pathway to hope and reason.
Neat. Well explained.
Fuckin maths … why allowing teaching it in schools while there is in this black world. … shoe, piss … exc … I suggest to close all colleges … better for children
Where do people with dyslexia that don't understand calculus stand in this equation?
at 2:03 the third equality holds because the ratio is equal to x/1 as theta varies, thus the limit must also be x and the last equality holds because of Pythagorean thm.
Why don't you explain
Well, you have to prove that alpha + sigma = 90 degrees
The deception on your school system starts at the time 1:38, and that is the real universe physic. Perception is Okay, where all the Earthy people comprehend only deceptive-perception.
Theta + alpha = 90 degrees. So the second alpha plus theta is tangent to the radius. This video is bullshit and you all are retards.
Wait I dont understand why does it become a straight line as delta titre approach zero? 0:53
Why does dY/dtheta = X/1? 1:47
is beatiful @€@
For me this demonstration proves nothing. It considers that the arc is a approximation of the circle when the angle is little. this is equivalent saying sin' = cos.
