Course Description
At College of the Redwoods, Math 30 is the course number for our College Algebra course. College Algebra is a transferlevel math course needed for preparation for the calculus series (Math 50ABC). Math 30 and Math 25 (Trigonometry) together constitute what is often referred to as "Precalculus". Most students take Math 30 before Math 25, but these two courses may be taken in either order or at the same time.
Prerequisites: Grade of C or better in Math 120 (Intermediate Algebra) or equivalent, or an appropriate score on the math placement exam.
Course Description: A course covering firstdegree and absolute value equations and inequalities;composite and inverse functions;polynomial, rational, exponential, and logarithmic functions; systems of equations and inequalities; matrices; sequences and series; mathematical induction; binomial expansion theorem; and complex numbers.
Textbook
The current textbook for the course is Algebra and Trigonometry (7th edition), by Sullivan, published by Prentice Hall, ISBN #0131430734.
This book can be used for both Math 30 and Math 25.
A limited number of textbooks are available on loan from the library. The textbook can also be purchased very inexpensively from various online book sellers.
 Recommended: Student Solutions Manual for the 7th edition, ISBN #0131430793
 Recommended: Student Solutions Manual for the 8th edition, ISBN #0132321246
Textbook Support
Correlation Guides. Because two editions of the textook can be used in the class, we've published correlation guides for sections and exercises.
Recommended Ancillaries. A solutions manual and accompanying support CD are also available:
 Student Solutions Manual for the 7th edition, ISBN #0131430793
 Alternatively, you can purchase the Student Study Pack for the 7th edition (ISBN #0131631837), which contains both the Student Solutions Manual and the CD Lecture Series
Graphing Calculator
Students are required to use a graphing calculator in the Math 120 course. Indeed, one of the student learning outcomes for the course is: Students should be able to use graphs and the graphing calculator to explore mathematical concepts and to verify their work. At the end of the course, students should be able to:
 Sketch the graph of a function, adjusting the viewing window so that all "essential behavior" of the function is visible in the viewing window.
 Use the calculator to find solutions of f(x)=0, f(x)>0, and f(x)<0.
 Use the calculator to find solutions of f(x)=g(x), f(x)>g(x), and f(x)<g(x).
 Perform linear regression.
Graphing Calculator Rentals: Students can rent a calculator for the semester for $20. Instructions are available at the following link:
Graphing Calculator Rental Program
Help for using the graphing calculator is available.
 Several instructors have pages dedicated to using the graphing calculator.
 For help constructing inline formulas, see the Optimath Syntax Checker page. Firefox required. If you are not reading this page in Firefox, simply drag the link Syntax Checker onto the Firefox icon.
Online Practice and Testing in Mathematics (OPTIMATH)
OPTIMATH is our locallydeveloped online practice and testing system. The portal for OPTIMATH is:
http://msenux2.redwoods.edu/optimath
There are numerous resources to assist students and instructors.

For information on how to get started, read:
 For assistance with Optimath Syntax, read Writing Mathematical Formulas in Optimath, then try your hand with our new Syntax Checker. Firefox required. If you are not reading this page in Firefox, simply drag the link Syntax Checker onto the Firefox icon.

For assistance in logging on to the OPTIMATH system, we have two videos, the second of which deals with names containing hyphens and apostrophes. Note: If you have the Flash plugin loaded, clicking links in the first column of the following table should start the video up in your browser. Use the links in the second column to save the file to your hard disk, then open the saved file in Quicktime or ITunes.
Flash format iPod m4v format 
If you are still struggling with OPTIMATH syntax, try watching these three videos. Note: If you have the Flash plugin loaded, clicking links in the first column of the following table should start the video up in your browser. Use the links in the second column to save the file to your hard disk, then open the saved file in Quicktime or ITunes.
Even if your instructor does not use OPTIMATH as a formal part of the course, your can still access the following online practice exercises:
