LAPLACE’S EQUATION IN SPHERICAL COORDINATES
www.dslavsk.sites.luc.eduIt is important to know how to solve Laplace’s equation in various coordinate systems. The coordinate systems you will encounter most frequently are Cartesian, cylindrical and spherical polar. We investigated Laplace’s equation in Cartesian coordinates in class and just began investigating its solution in spherical coordinates.
