Course Description

At College of the Redwoods, Math 30 is the course number for our College Algebra course. College Algebra is a transfer-level math course needed for preparation for the calculus series (Math 50A-B-C). 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 first-degree 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.


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.

Alternate version of the textbook: You can purchase the 8th edition instead (ISBN #0132329034). The 8th edition can also be purchased very inexpensively from various online book sellers.
