The first exam covers Chapter 1 (excluding Section 1.4) and Section 2.1.
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 90 minutes if needed.
Exam Review Session: Monday, Sept. 23, 7:30 - 9:00 pm in Smith Labs 154, led by our TA
Ken Goettler.
Note: You will be allowed a scientific calculator for the exam which does NOT have graphing
capabilities.
