Math Software  -> Graph Function (Graph Calculus) -> Graphing Parametric Equations
Function Grapher and Visual Calculus have the ability of graphing parametric equations. Parametric equations must be in one of the following forms:
2D Curve
   x=f1(u), y=f2(u)
   a=f1(u), r=f2(u)
3D Curve
   x=f1(u), y=f2(u),z=f3(u)
   a=f1(u), r=f2(u), z=f3(u)
   a=f1(u), b=f2(u), r=f3(u)
3D Surface
   x=f1(u,v), y=f2(u,v),z=f3(u,v)
   a=f1(u,v), r=f2(u,v), z=f3(u,v)
   a=f1(u,v), b=f2(u,v), r=f3(u,v)
                

The following figure shows the graph of 2D parametric equation a=10*(cos(u))^3, r=10*(sin(u))^3.

The following figure shows the graph of 3D parametric equation a=u, r=10*sin(u), z=u.

The following figure shows the graph of 3D parametric equation x=cos(u)*sin(v), y=sin(u)*sin(v), z=cos(v)+log(tan(v/2))+0.2*u
