# MA 1024 Lab 5: Volumes and double integrals

## Purpose

The purpose of this lab is to acquaint you with using Maple to do double integrals.

## Getting Started

To assist you, there is a worksheet associated with this lab that contains examples. You can copy that worksheet to your home directory with the following command, which must be run in a terminal window, not in Maple.

cp ~bfarr/Intdouble_start.mws ~


You can copy the worksheet now, but you should read through the lab before you load it into Maple. Once you have read to the exercises, start up Maple, load the worksheet Intdouble_start.mws, and go through it carefully. Then you can start working on the exercises.

## Background

### Volumes from double integrals

Suppose that is a rectangular region in the the plane, and that is a continuous, non-negative function on . Then the volume of the solid above and below is given by the double integral

You learned in class that such integrals can be evaluated by either of the iterated integrals

or

where the rectangle is defined by the inequalities and . The worksheet associated with this lab contains examples of how to use Maple to compute double integrals over rectangular regions.

## Exercises

1. Use Maple to compute the following double integrals.
