Gotta nerf Feynman's trick in the next math update

Is this not Leibniz theorem?

Great vid

suggestion: you could change the angle of the camera, use a marker instead of a pen, use a white paper, and maybe write more clearly. The quality of production just isn't on the right level and makes it hard to watch

Math

thanks for sharing the video with us! Always cool to see how people interpret identities and functions in their own ways. I like this explanation.

I'm not used to differential equations. Is Euler's formula really the only function that satisfies y'=iy ? Very compelling, though. The exponential side of it always felt disconnected to me, this helped them feel like they actually are the same thing

You sound so excited great explanation, btw

Thank you for this explanation

If you ever re-upload this video, it would be helpful to factor out “i” from the derivative (so people can more clearly see the beginning equation) and then to link the trig function to Euler’s number by saying that this pattern only forms with either of these equations and therefore they must be linked or the different forms of the same expression

Is this inspired by blackpenredpen’s video from a year ago??

very based

Correction: at 5:35, instead of np(1-p) >5, it should be just n(1-p) > 5 for a large sample
