A personalized collection of teaching tools, notes, and interactive materials for precalculus content. There are Topics/Tutorials, Math History, Enrichment, and other resources on this page. It also includes a link to the Google Site I created the last time I taught precalculus as an enrichment course to help students prepare for taking the course in the fall.
