The second exam covers Chapters 14, 15 and Sections 16.1, 16.2 and 16.3.
It is recommended that you 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 14, 15 and 16 Reviews and Check Your Understanding Sections below.
Note that these problems are a SAMPLE selection.
Certain topics are covered in the reviews better than others.
The odd answers are in the back of the book
while the evens are listed here. The exam will be designed to take the full class
period (45-50 minutes).
Exam Review: We will review for the exam on Monday, April 11, during class.
Please come prepared with specific questions.
