This page will have links to Mathematica notebooks and other files for your use.

Files with extension .nb require Mathematica to read and evaluate (or the free Mathematica Player just to read as is). Most of the Mathematica notebooks also require David Park’s Presentations add-on for Mathematica; Math 421 students will receive a free copy of Presentations for their personal use from the professor.
