How to make a mathematical dynamic graph?
I have seen a lot of mathematics teaching videos containing a lot of mathematical dynamic graphs; I think it is very interesting, and it is very attractive!
Such a video can help us have a good understanding of mathematics.
So what tool or software should I use to make such a mathematical dynamic picture and insert it into the video?
As an example of what I mean, I feel that one of the excellent teaching science videos is here, from 3Blue1Brown.
