Hypercycloid, hypertrochoid, hypocycloid, and hypotrochoid

March 6, 2019 blog math code

Hypercycloid, hypocycloid, and more general version, the hypertrochoid and hypotrochoid, are curves of the locus of a point on a circle rolling on a bigger circle. Like many other locus problems, it is convenient to tackle it from parametric equations. [more]
