Homework assignments Unless further notice, homework is to be turned in Fridays in class. You may be able to get the homework to the TA by other ways if it is OK with him.

Disclaimer: I will try to get the homework assignment on the net in time. Due to time and other limitations, this may not always be possible. The fact that there is no assignment posted for a particular date does therefore NOT necessarily mean that no homework is due.
