Abstract
A formula is derived which allows angular or hyperangular integration to be performed on any function of the coordinates of a D-dimensional space, provided that it is possible to expand the function as a polynomial in the coordinates x1,x2,...,xd. The expansion need not be carried out for the formula to be applied.
