Best ResponseYou've already chosen the best response.0so how do i apply G(x,y)=sin^5(xy^2) ?

Best ResponseYou've already chosen the best response.0Apologies, I misread the boundary function as the density function. \[\large \int\limits_{x=2}^{x=2}\int\limits_{y=0}^{y=\sqrt{9(1\frac{x^2}{4})}}\sin^5(xy^2)dydx+\int\limits_{x=2}^{x=2}\int\limits_{y=\sqrt{9(1\frac{x^2}{4}}}^{y=0}\sin^5(xy^2)dxdy\] I'm less sure about this one
