Can someone please tell me how to solve this double integral?
The following hint is given: Sketch the domain of integration.
I don't know the antiderivative of . I tried to guess a couple of antiderivatives, but none of their derivatives were equal to .
Is there something else I should do first (and how)?
Update: I tried switching dydx to dxdy, which results in
But this seems even worse, because the variable boundary is now on the outer integral.
Please help! I still can't solve this one.
