The homepage for the Precalculus I course has been changed as of May 2012. The current page may be used for Summer 2012, but you will probably prefer the new page. In any case, neither page is to be used without completing the Startup and Orientation.
Starting Summer 2012 the menu-driven page at the link
will be used for startup and orientation to the course, including the course homepage, assignments, due dates, course of study, communications and much more.
