# Precalculus

I am teaching this particular version of this Precalculus course for the second time this semester. Most of the activities were cowritten by Paula Shorter and I during Summer 2008. This work was inspired by the Precalculus course that had been taught for some time at Rockhurst University at that time. Some recent additions come from the work of the Mathematics Assessment Project (http://map.mathshell.org/) and our colleague Dr. Keith Brandt and are referenced accordingly. All word documents should be downloaded to see all of the notation correctly.
