Precalculus Tutorial

This tutorial has been ported to a new domain. Please change your links to this resource from "" to "" Direct inquiries to Prof. Bales

This course assumes the student has a good grounding in basic school algebra. Students who diligently follow the instructions and examples and work the exercises should have a good grounding for a first course in calculus.

Prof. Bales is beginning the process of updating this site, written in 2000, to modern technology. The site was moved several years ago to and the site here at will soon be shut down. Look for a much improved appearance of the site sometime in the Fall of 2012.
