## Helmholtz Differential Equation--Conical Coordinates -- from Wolfram MathWorld

Surfaces of constant r are spheres of that radius centered on the origin. In this coordinate system, both Laplace's equation and the Helmholtz equation are separable. The scale factors for the two conical coordinates are. Gradient, Mathematics, Curvilinear coordinates, Quantum mechanics, Cartesian coordinate system.

## Bessel function

Let us first state exactly what this book is and what it is not. It is a compendium of equations for the physicist and the engineer working with electrostatics, magne- tostatics, electric currents, electromagnetic fields, heat flow, gravitation, diffusion, optics, or acoustics.

It tabulates the properties of 40 coordinate systems, states the Laplace and Helmholtz equations in each coordinate system, and gives the separation equations and their solutions. But it is not a textbook and it does not cover relativistic and quantum phenomena. The history of classical physics may be regarded as an interplay between two ideas, the concept of action-at-a-distance and the concept of a field.

Newton's equation of universal gravitation, for instance, implies action-at-a-distance. In most cases, the field approach has shown itself to be the more powerful.
