Evaluate ∫∫D sin(x) / x dA, where A is the triangle with vertices (0, 0),(0, 1),(1, 1).
The Attempt at a Solution
I've set up the integral, with x≤y≤x^2, 0≤x≤1 for the upper and lower bands of each integral. dxdy
I'm not sure how to go about it though.
I can re-write the integral to be sin(x)*x-1 and do integration by parts but I get stuck in a loop. Is there some method of integration I should be using instead?
