Nice graphics. Good speaker. Interesting problem. Whenever I see pi involved I know there is a way to make a circle somehow in the calculations. Let me think about it.

All of the videos from 3Blue1Brown has these nice graphics.
His series on linear algebra explains it so intuitively with the graphics. It should be taught this way in school: https://www.youtube.com/watch?v=fNk_...2xVFitgF8hE_ab He also have a series on calculus I have not watched yet: https://www.youtube.com/watch?v=WUvT...53DwVRMYO3t5Yr
