# Homework

In case you miss a homework assignment in class, you can find it below. Unless otherwise specified, all problems are from the 2nd Edition of University Calculus: Early Transcendentals published by Addison Wesley (Pearson). 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 there; use Course ID `bartels18672`. (However, MyMathLab is not required for this section.)
