Let R be the region in the first quadrant of the xy-plane bounded by the hyperbolas xy = 1, xy = 9, and the lines y = x, y = 16x. Use the transformation x = - , y = uv with u > 0 and v > 0 to rewrite the integral below over an appropriate region G in the uv-plane. Then evaluate the uv-integral over G. - + Wxy dxdy R + Wxy |dxdy = (Type an exact answer.) R
