double integral (D) of y^3(x^2+y^2)^(-3/2) DXDY where (D) is the region determined by the ocnditions .5 less than or equal to y less than or equal to 1 and x^2+y^2 less than or equal to 1.
Have you drawn the region of integration? It's the interior of the unit circle that lies above the line y = 1/2.
One possible set up is .
Another is .
But you should consider switching to polar coordinates. In which case you'll need to express the line y = 1/2 in polar coordinates. Note that .
