# Epicycloid type 2D curve

*From*: "Narasimham" <mathma18@xxxxxxxxxxx>*Date*: 14 Feb 2006 03:42:41 -0800

What is the best parameterization of the epicycloid type smooth 2D

curves with curvature = -1/r^2 ? ( r is radius to any point from

origin). Some of these ( maximum radii .2,.4,.6 ) are indicated :
