Homework Assignments

Homework is optional. The problems marked with an asterisk (*) may be handed in to have your solution checked by one of the graders, but there will be no credit counting towards your grade. If you decide to have your problem set graded, turn it in with your quiz.
But remember: Quiz questions will be mostly based on the preassigned set of homework problems.

The solutions are in PostScript format. If you do not know how to view or print PostScript files, click here. If you have still problems or questions, send me an email.
