In geometry, a curve resembling a series of arches traced out by a point on the circumference of a circle that rolls around another circle of a different diameter.
In geometry, an epicycloid is a plane curve produced by tracing the path of a chosen point of a circle — called an epicycle — which rolls without slipping around a fixed circle ...
The path traced out by a point P on the edge of a circle of radius b rolling on the outside of a circle of radius a. An epicycloid is therefore an epitrochoid with h=b.
Epicycloid. Parametric Cartesian equation: x = (a + b) cos(t) - b cos((a / b + 1) t), y = (a + b) sin(t) - b sin((a / b + 1) t) Click below to see one of the Associated curves.
