### Maple

We will use Maple extensively for calculations and programming in this course. Much of the course is about how Maple works. 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
