Question

Evaluate , where is the trapezoidal region with vertices given by , , , and ,

using the transformation , and .

Answer

The first thing we have to do is figure out the general equations for the lines that create the trapezoid.

Now we have the general equations for out trapezoid, now we need to plug in our transformations into these equations.

So our region is a rectangle given by ,

Next we need to calculate the Jacobian.

Now we can put the integral together.
