So I'm finding this problem difficult:

What is the area of the region in the first quadrant (upper right quadrant) bounded by the curves y = sin(x)cos^2(x), y = 2xcos(x^2), and y = 4 – 4x?

I keep trying it, and graphing it on my calculator but I'm getting different answers every time. Sometimes I'll get around .38 other times I get 1.8 I'm not sure what I'm doing wrong and what I should be getting?

Thanks for your help!
