# Problem #3: Consider the double integral Jp x dA, where R is bounded by the lines y=2x- 1, y = 2x + 1, y = 1-x, and y 3 - x. X- 1-y メニ g(u, v) and y h(u,v). Define an 2xrl 42x-1 appropriate transformation of the form x = a. 1-x>2x1 23 (o,) 3-x 3-x-2 2-3x b. Find the Jacobian of your transformation. Evaluate the integral using your transformation. c.

Question

How do I choose  my g(u,v) and h(u,v)?
