    Q: How do you integrate (sinx)^3 dxy?

    We must first complete the square for both equations and get the equations in the (x-a)2+(y-b)2=r2 with the primary objective of determining the centres of both circles (a,b) . Through completing the square twice (once for x, once for y) for the equation of the first circle (x2 -2x + y2 - 2y = 7 ) we arrive at (x-1)2- (-1)2 +(y-1)2-(-1)2 =7.
