  We didn't get to this in class, so it's now a homework assignment.

• By this time, you should be able to do any of the problems in Chapter 1 of our textbook. I expect that you have read the chapter and tried the examples worked out all of the "Concept Checks", "Study Checks", and "Sample Problems" on your own. The answers for all of these are at the end of the chapter. I also expect that you have worked through several of the odd-numbered "Questions and Problems" within and at the end of the chapter. You'll find the answers to the odd-numbered questions and problems at the end of the chapter as well.
• If you have any trouble with any of these practice problems, please ask me some questions either during class, via email, or during the lab period.
