We can compute double integrals as iterated integrals in Maple just as we would by hand:

With the MultiInt command in the Student[MultivariateCalculus] package we can cut down on the typing and number of parentheses required:

Even Maple can struggle with double integrals!

Sometimes Maple has the same problem we do when trying to perform the integration in a particular "given" order. For example, consider the iterated integral of the function

There are times when reversing the order of integration will not enable you or Maple to solve a particular problem. When this happens, you either give up or turn to a numerical approximation method such as approximating Riemann sums.

Some regions in the plane that are not easily used as the region of integration of iterated integrals in rectangular coordinates. Switching to an integral in polar coordinates may make the problem much easier.

Rules for polar integrals:

The double polar integral should be expressed as follows:

1. Draw a sketch of the region R of integration.

2. Interpret this region in polar coordinates.

3. Shoot a ray from the pole (origin) out through the region. The entry point into the region R becomes the lower limit for the inner integral. The exist point from the region R becomes the upper limit for the inner integral. These limits MAY depend on \316\270, but not r.

4. The outer limits should be the minimum to maximum values of \316\270 that generate the entire region R.

5. Don't forget the r in the integrand !
