Plane Curves: Hypotrochoid


A Hypotrochoid is a roulette traced by a point P attached to a circle of radius b rolling around the inside of a fixed circle of radius a, where P is a distance h from the center of the interior circle. There are four curves which are closely related: the epicycloid, the epitrochoid and the hypocycloid.
