How do you find the center of gravity of the region between the graphs of f (x) = cosx and g (x) = sinx on [0, pi/2]?

I got Msubx = 0, Msuby = - 2, and Area = 0. But that can't be right, as that would make the center of gravity (-2/0, 0), and that's obviously wrong. I think it has something to do with the areas of cosx and sinx canceling out, but I don't know what to do with it - how do I not get an area of 0? Also, I suspect I made mistakes with Msubx and Msuby but can't figure out where.
