hi...i am stucked at integrate this term: $\displaystyle \int{\int{x^py^q\sqrt{x^2+y^2}\:dx}\:dy} $ wher p and q are constant. anybody can help me on this? Thanks

Have you tried in polar coordinates? it becomes $\displaystyle \int \int r^{p+q+2}\cos^p\theta \sin^q\theta \ dr\ d\theta$ (I haven't tried, but it looks a bit easier. Just suggesting.)
no bounds, this makes no sense by not having them.
sorry..forgot to put the boundary. the boundaries for x and y is -1 to 1. thanks
