Let Rxy be the quadrilateral in the x-y-plane with vertices
(0, 0), (2, 1), (1, 2) and (3, 3).
(i) Draw the quadrilateral Rxy carefully, and find the equations of all the lines
forming its boundary.
(ii) Express the double integral Rxy
f(x, y) dx dy as an iterated integral. You
can use either order of integration. And since I did not give you a specific integrand,
I'm not expecting you to evaluate the integral--you can stop after setting up.
Now consider the transformation
T(u, v) =
u + 2v
2u + v
from the u-v-plane to the x-y-plane.
