SCHEDULE

This page lists the dates of all the lectures with links to slides and examples from the lecture (if any). Readings are in the electronic book College Algebra, Seventh Edition, by Stewart, Redlin, and Watson To get the most out of lectures, skim the reading beforehand. You may also want to print out the slides before lecture so you can write on and/or highlight them during lecture. After the lecture, go back and read the pages carefully and try some of the exercises at the end of the chapter yourself. (This will not be graded but will help solidify your understanding of the material.)
