## Maple

Maple is a mathematics and computer algebra software package that we will use from time to time in this course. It can be downloaded from Dartmouth's Download page for both Mac OS X and Windows 2000 and XP Professional. Note that if you download Maple from Dartmouth, you must have KeyAccess installed on your computer, as well as a connection to the Dartmouth network, to run Maple.

Maple is pretty user-friendly, so it should not be too difficult to figure out how to do what you want to do, provided you make use of its help menus. Here are some things to keep in mind when you use Maple (From now on, Maple commands will be in monospace font):
• You can ask Maple for help with certain functions by typing ? followed by the name of the function with which you want help as Maple Input (displayed in red following a >) and then hitting "enter" or "return." For example, if you want help with the "Matrix" function, type ?Matrix and hit enter.
• Be sure to end every command you give Maple with a semicolon ; (otherwise, you will receive a warning message). To suppress Maple output, end your command with a colon : rather than a semicolon.
• After opening a Maple worksheet that you've saved, you must hit enter through every command in the saved worksheet (in other words, put your cursor in the middle of each command and hit "enter") if you want Maple to have those commands in its memory.
• You can use the % command when you do a computation in the previous line and want to do something more with it. For example, if you added 25 and 30 in one line, and then you want to divide this sum by 5, your Maple Input would look as follows:
> 25 + 30;
55
> %/5;
11
Most of our work in this class will require the Linear Algebra package, which you input as with(LinearAlgebra);. The code for the Maple worksheets we use in class will be posted on this page throughout the term. Feel free to use Maple to do your homework, but make sure you show all the steps you use; otherwise, if you give an incorrect solution, you will get a 0.
