In polar coordinates, the family of minimal surfaces can be parameterized by


where n is the degree of the surface, and t is a parameter that creates a family of surfaces.


Tangent Planes:

At u = u0, v = v0, the tangent plane to the surface is parameterized by:

Infinitesimal Area:

The infinitesimal area of a patch on the surface is given by

Gaussian Curvature:
