Prolate Spheroidal Coordinates
... Prolate spheroidal coordinates are a three-dimensional orthogonal coordinate system that results from rotating a spheroid around its major axis, i.e ... Rotation about the other axis produces the oblate spheroidal coordinates ... Prolate spheroidal coordinates can be used to solve various partial differential equations in which the boundary conditions match its symmetry and shape, such as solving for a field produced by two centers, which ...
