Textbook

Ideals, Varieties and Algorithms by Cox, Little, O'Shea

Software

We will use Maple extensively for calculations and programming in this course. The university has a site license. 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 the microcomputer store for about $180.

The following Maple worksheets are from the course.
