Homework, due 10/18/2006:
a) Read Ch 4-5, take online quiz
b) Using content of 4-4 and 4-5 as a source, make up 5 questions with a separate worked out answer key for sharing with your classmates. Don't copy problems out of the text: make up your own problems. I drew a diagram on the board of what you need to turn in, so be sure you do the right thing.
