I create math animations without words (as few words as possible).
My dream is to bring "Proofs Without Words" to life.

Taylor Polynomials Tango
Animation: Hua-lun Li, Music: Nando Monica
This animation is about Taylor polynomials on y=1-sqrt(1.1+sin(x)).
The coefficient's sign of the highest term changed between positive and negative
as the base point moving on x-axis.
I think it is unique because (1) Everybody laughed when I show this in my calculus class
(2) There are questions can be discussed with students as I pause the animation at different time.
