Poisson Equation Analytical Solution

Hi,

Does anyone know how to solve the following for an analytical solution?

- nabla . sigma (u) = f

if

u = sin(pi*x)sin(pi*y)
v = sin(pi*x)sin(pi*y)

?
I know that I need to assign a value for u and v and then get values of x and y, but I'm not sure what to do afterwards!

Many thanks !
