### Maple

We will use Maple extensively for calculations and programming in this course. SFU has a site license for Maple. Maple is installed on the PCs and MACs in the assignment lab, the CECM lab, university open labs and the library. Maple is available from Maplesoft for a very good price at Maple 18 for Canadian Students for \$99. I have obtained a discount code for the class for 25% which I will give out in class.

The following Maple worksheet [ in Maple worksheet format (.mws) and Adobe PDF format (.pdf) ] contains notes for how to use Maple. Please read through this even if you have used Maple before.
