The second exam covers Chapter 2 (excluding Sections 2.1 and 2.2) and Sections 3.1 and 3.2. It is recommended that you go over homework problems (HW#4 - 6), your class notes and the quizzes. Many of the problems and questions we discuss in class are excellent examples of test questions. The solutions to your WebAssign problems on HW#4 - 6 can be seen by clicking "View Key" near the top of each assignment. I have also listed many, many practice problems on WebAssign titled ``Exam 2 Review Problems.''

In addition, some good review problems from the Chapter 2 Review Exercises are listed 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 roughly one hour although you will have the full class period (plus a little extra) if necessary.

**Exam Review Session:** Wednesday, Oct. 30th, 8:00 - 9:30 pm in Swords 302, with our TA
Meg Norton.

Please come prepared with specific questions.

** Note:** You will be allowed a scientific calculator for the exam which does NOT have graphing
capabilities.

Also, extra credit will be given out for wearing a
halloween costume to the exam.

**Chapter 2 Review Exercises, pp. 165 - 168**

Problems: 1, 3, 4, 5, 7, 9, 10, 13, 14, 16, 18, 21, 25,
29, 30 (a and b), 33, 34, 35, 36, 37a, 39, 40, 41, 42, 45

The answers to the evens are:

4. 0

10. -1

14. 1/3

16. 0

18. -1

30. (a) f'(2) = 10, (b) y = 10x - 16

34. Your graph should be positive (above the x-axis) until a
small positive x-value, then become negative (below the x-axis).

36. Your graph should be discontinuous at the cusp since the function
is not differentiable at that point.

40. a = f, b = f'' and c = f'.

42. The first derivative of the cost of living function is positive since the
cost rises but the second derivative is negative because it is rising
at a slower rate (slopes decreasing means concave down).
