Integration of a function

Please login with a confirmed email address before reporting spam

Hello,
I am having trouble integrating a function over a surface for which I have solved variable p
.
The integration I want to solve is

f(x,y) = int (p * f2(x,y,x',y') dx' dy'.

The problem I have encountered is keeping the x and x' (and y and y') terms separate in the integration. f(x,y) is actually a function of the Euclidean distance between the x,y coordinate and the x',y' coordinates which are then integrated over the surface.
Any help would be most gratefully received!
Thanks,
Rob
