Plotting complex functions

I wrote a blog post of sorts, spread over several tweets, about plotting functions of a complex variable.

Plot of cosine over a square centered at the origin of the complex plane.

Color = phase.

Height = magnitude.

First Weierstrass’s elliptic function.

And a phase plot for z5.
