Math 31a Winter 2010
Homework Assignments

Homework assignments are to be turned in during class on the day that they are due (either at the beginning or end of class, not in the middle!). You may turn an assignment in early by giving it to the professor or your TA before the due date. NO late homework will be accepted, but the two lowest homework scores will be dropped. You are allowed to work in groups on the homework but ultimately you are expected to be responsible for writing up your homework (and of course for understanding it). Further, the homeworks should be neatly written and legible, you can lose points for the homework being poorly organized, illegible, and of course for having incorrect answers.

Below we also give some "suggested problems". These are not meant to be turned in and will not be graded. While they will not be graded it is strongly encouraged that you look and think about these problems (you do not need to limit yourselves to these problems, go ahead and do all of them!). The more practice you have in doing homework and working on problems the more you will develop confidence and skills in doing the problems which will be helpful during the exams.
