Computer Resources

There are many computer resources that will assist students in their math courses. Make an appointment with the Math Lab Coordinator to learn to use:

Plato Tutorials (in all levels of Math and in Chemistry, Biology and Physics)
CD lecture series (for most math courses)
MyMathLab (Web resource with practice tests and assignments graded by the computer
Internet Resources

Math Links on the Internet
Graphing Calculator Resources
Graph Paper Generator

MyMathLab This Web-based resource is full of

• practice tests and assignments that are graded by the computer (you get immediate feedback) and that are exactly like the textbook problems
• video tutorials

It must be purchased with a new book, or purchased as an extra with a Used Text. (Contact the Bookstore.) If your instructor does not use MyMathLab ask the Math Lab Coordinator how to use it.

CD and Video Lecture Series

Video (on CD) of math textbook authors lecturing on the textbook topics and doing sample problems are available in the Library (ask at the Circulation desk). Extra copies are available from the Math Lab Coordinator. Most math textbooks have this resource.

There is also a video Calculus Lecture Series available for loan.
