Homeworks
Two different kinds of homework problems will be assigned in this course.

Ungraded problems are not to be turned in, but you are expected to solve them carefully, in great detail; failure to so may result in an inability to understand the course material. Answers to these problems are usually contained in the back of your textbook. Don't peak, though! If you simply look up the answer before seriously trying to find the solution, the only person you will be cheating is yourself.

Homework sets, by contrast, will be typically assigned weekly and due on Monday in class. They will be posted on this web site. (NOT on blackboard site!) Late homework will not be accepted. However, grades for homework assignments may be dropped in cases of documented medical problems or similar difficulties.
