[SOLVED] Centroid Parabolic area
http://img227.imageshack.us/img227/7518/slowge9.th.jpg
Find the centroid of the area.
I'm not quite sure what I'm screwing up on this problem, I can do other problems like when y = x^2. I have only shown my work for the x centroid, but I can't seem to get the answer (3/8b). Does anyone see where I messed up, I assume it's somewhere in the integral setup. I think dA = h-y dx is correct.
