It is NOT an acronym of hyperbolic paraboloid.
Rotate a hyperbola about the line joining the two foci.
If the skirt of the paraboloid is a circle of radius 'a', the equation in Cartesian co-ordinates of the two are:
Natural cooling towers are designed for hyperboloid shape. The advantages of it are:
The quadratic surface of a hyperbolic paraboloid is given by either of the two Cartesian equations:
The parametric equation is given by
The shape of Pringles potato chip is hyperbolic paraboloid.
