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.)
