So im trying to solve this problem, and im having serious issues setting up the integral. What is given is:

SS (1/(x^2 + y^2)^2) dxdy, where the region is determined by the conditions x^2 + y^2<=1 and x+y>=1.

Im guessing I have to use polar coordinates for this, when I try this I get :

SS (1/r^2cos^2 + r^2sin^2)^2) r drd(theta) since x=rcos and y=rsin and JAcobian is r. and since sin^2+cos^=1 I get:

SS 1/r^3 Which I dont think is right under the boundaries I am using, any help?

(and yes I have tried to draw this unit circle out with the restriction but it does not help)
