What is the parametric equation of a sphere?
One common form of parametric equation of a sphere is:
#(x, y, z) = (rho cos theta sin phi, rho sin theta sin phi, rho cos phi)#
Since the surface of a sphere is two dimensional, parametric equations usually have two variables (in this case
If you are determined to have a parametric equation with just one variable
Such a surjection can even be made continuous. I'll see if I can put together a simple short formulation.
