Math 121       Study Guide for Hour Quiz #2         C.S.Davis

You are responsible for the subject matter in the three chapters and sections below. The following topics are the most important. Typical exercises from Basic Technical Mathematics with Calculus, 7th ed, by Allyn J. Washington are assigned at the end of each objective. Work additional exercises if you need more practice. The answers to the odd numbered problems are in the back of the text.  These exercises are for practice and are not graded.  The problem sets found on the Algebra&Trig Welcome Page are graded in class.  See the Semester Plan for the current dates for the grading of the problem sets and taking of the hour quizzes.
