**Homework assignments:**

All students taking the course for credit are required to do the homework. Unless otherwise announced, homework will be
due on Thursday at 5pm.

Homework should be handed into the box outside of the Ann 232 by the due date, or emailed to Tian <twang3@caltech.edu> if you type it up. Please use a large font or write legibly.

You may receive partial credit if you describe a thoughtful approach to the problem, even if you are unable to solve it completely.

If you have questions, you may post them on Moodle or email them to Tian. Problem solutions will be posted on Moodle.
