The second exam covers Chapter 3, Chapter 4 (excluding Sections 4.4, 4.7 and 4.8), and Sections 5.1 - 5.6. It is recommended that you go over the homework problems (HW#4 - 7) as well as your class notes. Many of the problems and questions we discuss in class are excellent examples of test questions. I have also listed some sample problems from the Chapter 3, 4 and 5 Review Exercises below. The odd answers are in the back of the book while the evens are listed here. The Concept-Check at the end of each chapter (before the exercises) is also a source for good questions. The exam will be designed to take the full class period (45-50 minutes).

**Exam Review:** We will review for the exam on Monday, Oct. 30th, during class.
Please come prepared with specific questions.

** Note:** You will be given a scientific calculator for the exam which does NOT have graphing
capabilities so be prepared to answer questions without your personal calculator.
