Homework Assignments and Midterm:

Grading policy:

We are aiming for a 1 week turn around on grading homework. At the time we give them back to you, solutions will be available in printed form in a binder that I'll keep, but you can make a copy. Turn in howework on time for full credit. If you turn it in within a week late, we take off 20%. Once the solutions are available and others have theirs graded, then it's too late. If there are extenuating circumtances, please let me know.

Lecture Notes

While these notes are primarily to help me give my lectures, I'm posting them to help you fill in things you may have missed in class or to show the details of calculations we don't have time to work through. If you have any constructive input on how to make these more useful to read, let me know.
