The third exam covers Sections 6.6 - 6.8, 7.1 - 7.3 and 8.1 - 8.3.
It is recommended that you go over homework problems (HW #7 - 9), your class notes (including worksheets and handouts), and the quizzes
(Quiz #9 solutions are available here.)
Many of the problems and questions we discuss in class are excellent examples of
test questions. The solutions to your WebAssign problems on HW #7 - 9 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 #3 Review Problems.''

In addition, some good review problems from the Chapter 6, 7 and 8 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:** Tuesday, April 29, from 8:00 - 9:30 pm, in Swords 359 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.

**Chapter 6 Review Exercises, pp. 488 - 490**

Problems: 27, 32, 33, 37, 39

The answer to the even problems are:

32. (2, 2/3)

**Chapter 7 Review Exercises, pp. 548 - 550**

Problems: 1, 3, 4, 5, 6, 7

The answers to the evens are:

4. (a) y(0.4) = 1.08, (b) y(0.4) = 1.129238,
(c) y = 1/(1-x^2), y(0.4) = 25/21 = 1.190476 so decreasing the step-size leads
to a better approximation although it is still considerably off.

6. x = c e^(t - t^2/2) - 1

**Chapter 8 Review Exercises, pp. 629 - 630**

Problems: 1, 3, 4, 5, 9, 10, 13, 14, 19

The answer to the even problems are:

4. divergent

10. divergent (compare with Harmonic series)

14. divergent (nth-term test)
