You are expected to read the textbook both before and after each class meeting. Some of the homework depends on carefull reading of the textbook and at the beginning of each class meeting I will assume that you have at least glanced the setion that is to be covered ahead of time.
Homework: Homework from the text will be assigned at the end of each class. It is essential that you do the homework. In each homework set there will be some designated problems, appearing in bold font in the table bellow, that you have to turn in. Ocassionally there may be some additional handouts with homework that you have to turn in.

Midterm | 30% |
Final | 50% |
There also will be some projects assigned for extra credit.
