Hi, I've just read through a section on curvilinear coordinates and I would like to know how I could go about doing the following question.(adsbygoogle = window.adsbygoogle || []).push({});

Q. Solve Poisson's equation [itex]\nabla ^2 f = c[/itex] where c is a constant and assuming that f = f(r) depends only on the radius [itex]r = \sqrt {x^2 + y^2 + z^2 } [/itex].

Note: This question shouldn't require any knowledge of how to solve PDEs. Knowledge of the content of the curvilinear coordinates topic should be enough.

If someone could point me in the right direction that would be good thanks. I don't need a full solution, just the essential ingredients which will allow me to complete this question. Any help would be good thanks.
