The first exam covers Chapter 1 (excluding Sections 1.4 and 1.7) and Sections 2.1 and 2.2. It is recommended that you go over homework problems (HW#1 - 3), 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#1 - 3 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 1 Review Problems.''

In addition, some good review problems from the Chapter 1 and 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, Sept. 25th, 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.
