In the syllabus you will find our class contract: what the goal of the course is; what I plan to cover; how I plan to assign grades; etc. version)
In the course outline, I list the tentative schedule for each lecture. This page will be updated throughout the semester.
A word on academic honesty: if you are having trouble in this course, you are encouraged to come to office hours, or to work in groups. You are not encouraged to copy. The prudent student will take the time to learn the difference.

(09/26/07)  Homework Hints Updated to include comments on sections 3.3 and 3.4.
(09/20/07)  No homework due Tuesday. It is due Thursday instead.
Look at the supplemental problem this weekend to be sure you understand what I want.
(09/20/07)  I've gotten a few requests to post future homeworks earlier, so I'll make an effort to do that.

When do you want homework due, in general? Give me some feedback, and I'll reassess our current scheme---bear in mind that if you say 'Thursdays' you'll be committing to working exercises from material 7 and 2 days old (not 7 and 11 days old).
(09/14/07)  New homework assignment and hints posted.
(09/06/07)  I finally updated the Homework Hints page below. Hope it helps. Again, you can find guidance on writing up "theoretical" solutions here.
(08/26/07)  If the Homework Hints page below does not suffice, you can find additional help on the more "theoretical" exercies here.
(08/26/07)  I've finally gotten started planning the course. Expect lots more information shortly.


As outlined in the "course syllabus" above, the homework below will is due at the beginning of class on the dates indicated below. No late homework will be accepted, but only the best 8 will be kept in considering your final grade for the course.
