Catenoid Minimal SurfaceWritten by Paul BourkeDecember 2000
y = c cosh(v/c) sin(u) z = v 0 <= u <= 2pi infinity <= v <= infinity
The Catenoid is the only minimal surface (zero mean curvature) that is also a surface of revolution. It was first documented by Leonhard Euler around 1740 making it the oldest documented minimal surface.
