Homework Statement
Change the order of integration in the following double integral
integral from o to a, integral from 0 to sqrt(2ay-y^2) f(x y) dx dy
so i can see its a semi circle with center at (0,a)
x= sqrt(2ay-y^2) can be expanded by squaring both sides. then completing the square x^2+(y-a)^2=a^2 which is a cirle of radius 'a', center at (x,0)
then I am not sure what to do.. how do i integrate with respect to y first,,then x? how do i set this up
