Let's say you have the mass of an object as a function of position, how would I go about finding the mass density as a function of position? I want a general answer, one that doesn't assume the mass has uniform density (that would be trivial).
As an example, can you solve this?
Say you have a ring of radius 1 with its center at the origin of a cartesian coordinate system. You are given that the mass [itex] M(x,y) = \frac{4}{\pi} x y [/itex]. Find the mass density of the ring.
The reason I want to do this, is to find the total mass of some object given the mass as a function of position, but in order to do the necessary integral it seems I need the mass density.
Any help would be greatly appreciated
