In the previous section we looked at double integrals over rectangular regions. The problem with this is that most of the regions are not rectangular so we need to now look at the following double integral,

Double Integrals over Rectangular Regions ... Double integrals arise in a number of areas of science and engineering, including computations of ... In this section we consider double integrals over more general regions. Suppose that the region R is defined by G_1(x)<=y<=G_2(x) with a<=x<=b. This is called a vertically...

Computing either of the double integrals should give the answer 44. Note that this example is simple enough to do by hand and certainly does not require the power of a computer or even a calculator.

Evaluating Iterated Integrals ... We will now address the problem of determining limits for a double integral from a geometric description of the region of integration. While MATLAB cannot do that for us, it can provide some guidance through its graphics and can also confirm that the limits we have chosen define the region...

We begin by exploring the procedure your helper application uses to evaluate iterated double integrals. You will find a discussion of this for your particular system in the worksheet.

The double integral has many interpretations other than volume. In this section, we examine several of those different interpretations. ... Evaluating the double integral leads to ... That is, the total mass is the double integral over the region of the mass density.
