I'm having troubles starting this problem. In the previous problems we have had, our transformation has been given to us (i.e something like x=u+v,y=u-v etc...). Since one is not given here do I just use x as u and y as v? Any help with this nasty would be greatly appreciated.
Evaluate the integral where R is the rectangle enclosed by the lines
x - y = 0,
x - y = 2,
x + y = 0,
x + y = 3.
Use a change of variable and a Jacobian.
