Math 221 Homework -- Spring 1999

This is the MINIMUM amount of exercises that you should attempt. If you have trouble with these, try some simpler ones in the book to identify what is stopping you. All odd-numbered exercises have solutions in the back of the book, BUT always TRY HARD to solve them on your own before looking at the solutions.

Below is a list of suggested exercises. The problems you must hand in are listed HERE.
