# Homework

In case you miss a homework assignment in class, you can find it below. Check the dates; there may be more than one section (or none) assigned on a single day. (Undated assignments are tentative.) Unless otherwise specified, all problems are from the 9th Edition of Algebra and Trigonometry published by Prentice Hall (Pearson). When I return graded homework, I may post some solutions here too; see the downloading help if you have trouble reading them. (See the grading policies for general instructions on doing homework and how it will be graded.)
