The second exam covers all of Chapter 2 and Sections 3.1 - 3.4 of Chapter 3. The exam will be designed to take an hour but you will have an extra 30 minutes to check your work.

A concise list of topics for Chapter 2 is given in the Chapter 2 Summary (p. 103). In Chapter 3, topics include the power, product, quotient and chain rules, how to differentiate sums, differences and constant multiples, and the derivatives of polynomials and exponentials. You should go over the homework problems 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 2 and 3 Reviews as well as the Chapter 2 and 3 Check Your Understanding Sections below. Answers to some of the even numbered problems are provided.
