### Homework

Homework will be due every Friday in class, starting the first week (August 24). You may turn in your homework in advance to Prof. Martin's mailbox in the Math Department office (Snow 405) or office (Snow 623). Your homework should be as neat and legible as if it were typed, and all sheets should be stapled together. Homework turned in late will not be accepted. Your two lowest homework scores will be dropped.

As a general rule, material covered in class on Monday is fair game for the problem set due on Friday of the same week.

The current assignment is indicated in boldface. Subsequent assignments are subject to change until one week before the due date.
