The second exam covers Chapter 2 (excluding Sections 2.1 and 2.9) and Sections 3.1 and 3.2. It is recommended that you go over homework problems (HW #4 - 6), class notes, and worksheets. 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. You can also click on "Practice Another Version" to redo some homework problems.

In addition, some review problems from the Chapter 2 and 3 Review Exercises are listed below. The odd answers are in the back of the book while the evens are listed here. The exam will be designed to take roughly one hour although you will have 90 minutes if needed.

**Exam Review Session:** Tuesday, March 29, 7:00 - 8:30 pm in Smith Labs 155, led by
Jake Alofs.

**Note:** This is the room next to our usual classroom.
Please come prepared with specific questions.

** Important:** You will be allowed a scientific calculator for the exam which does NOT have graphing
capabilities. Please bring your own calculator with you to the exam.
