Here are links to the online materials
corresponding to a list of Precalculus topics.
Video clips and slide shows require QuickTime. The first link, ReadMe,
leads to a page from which QuickTime can be
downloaded, and which explains
everything.
Probably the most representative sample of various types of tutorials
that we have developed is contained in the page "Exponentials and Logarithms" , also in the page "Polynomials and
Rational Functions".
