## Paraboloidal 2

The Paraboloidal 2 coordinates are a three-dimensional orthogonal coordinate system (λ,μ,ν) that generalizes the two-dimensional parabolic coordinate system.

Similar to the related ellipsoidal coordinates, the Paraboloidal 2 coordinate system has orthogonal quadratic coordinate surfaces that are not produced by rotating or projecting any two-dimensional orthogonal coordinate system.
