so x=v/y implies v goes from -3 to 3 right
My double integral is (x+y)
where R is the region on the xy plane bounded by the lines
x+y=3, x-y=3, and the hyperbola x^2-y^2=3
(u=x^2 - y^2....v=x+y)
I calculated the jacobian d(u,v)/d(x,y) determinant to be 2(x+y)=2v
and the reciprical = 1/2v
I dont understand what the new integral is and its limits?
my book gives like one example then goes to the next section
