Abstract
A new non‐polar spherical co‐ordinate system for the three‐dimensional space is introduced. The co‐ordinate system is composed of six local co‐ordinate systems mapped from six faces of a cube on to the 2‐sphere. Weakly orthogonal and orthogonal spherical harmonics are constructed in this co‐ordinate system. The spherical harmonics are easily computable functions consisting of polynomials and square root of polynomials. Examples of finite Fourier series computations are given in terms of the new spherical harmonics to demonstrate their immediate applicability. Copyright © 2007 John Wiley & Sons, Ltd.
