Complex numbers are a fascinating area of mathematics. It’s my favorite 
playground. You find them everywhere, even in unexpected places.

It all depends on your level of math.

There are other pages on my website about them.



In fact, for epicycles, the hardest part is obtaining the <x,y> 
coordinates of all the points that make up the figure !
