Hyperbolic paraboloid equation

Description

The hyperbolic paraboloid (not to be confused with a hyperboloid) is a doubly ruled surface shaped like a saddle. In a suitable coordinate system, a hyperbolic paraboloid can be represented by an equation witch constants dictate the level of curvature and the way that the paraboloid opens down and up along the x-axis and y-axis.
