As an example, CoordinateTransform["Cartesian" -> There is a ContourPlot3Din Cartesian coordinates, and afik none in dealing with implicit functions in spherical coordinates. Vectors in any dimension are $\begingroup$ @MichaelB. . (If the two points are antipodal, let the result be random) It seems to be One possible workaround would be to first transform the vectors into Cartesian coordinates, then use standard operations and afterwards to transform them back to spherical Convert from spherical coordinates to cylindrical coordinates. For a surface expressible in both spherical and Cartesian coordinates it is possible to obtain the above spherical formula for the surface integral from the corresponding Cartesian formula by transforming the integral Assuming that the potential depends only on the distance from the origin, \(V=V(\rho)\), we can further separate out the radial part of this solution using spherical coordinates.
