Homework
In case you miss a homework assignment in class, you can find it below.
Unless otherwise specified,
all problems
are from the 9th Edition of Algebra and Trigonometry
written by Sullivan and 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.
You can always do more homework problems!
You may need to practise the material
if you want to remember it
for the final exam,
a subsequent course, or the rest of your life.
If you bought MyMathLab access with your course textbook (or separately),
then you can find supplementary problems
through the
Moodle page.
(However, MyMathLab is not required for this section.)
