More information is needed for me to answer this question, what do you have and what do you want to do?

Can you convert the Cartesian coordinates into polar and work from there?

If your function lies on a plane with only one variable it is straightforward by translating the function to the origin. Otherwise you need spherical coordinates and may need to solve partial derivatives.
