Very good visualisation. My classes always try to explain function properties using the diagram chasing, as well as stuff like the conditions for an inverse and composition to exist.
Did you hear about the mathematician that couldn't prove f was surjective? **Epic** fail... Thanks for helping me understand a little more about diagram chasing than jokes from category theory!
Great visualization. Btw do you intend to make visual understanding of some theorems in Real Analysis? As an undergraduate that lacks proof background this class hurts me
Haven’t thought of doing them yet. I did use the software to show certain concepts in real analysis a few years ago but I was brand new to the software so I wasn’t doing things quite right.
I'll see if I can do a follow up, but I bet you can do it on your own! Also, this video doesn't seem to be as interesting to people as others by clickthrough rate.

That’s good! It’s really the best way to make sense of those types of proofs.
The video presentation is very intuitive, and it seems the order of differentiation for composite functions follows a similar pattern.

appreciate the animation!
👍
very nice
Thanks
Why dont you make videos of all the theorem.
It will help us to understand maths very effectively, including the 2nd one in the video.

do you have proof solution for the theorem at the end of the video?
I don’t. I bet you can work it out using this as a model though …
How call this theorem?
