### Course Descriptions

#### MATH 117 and MATH 118 College Algebra in Context I & II

Prerequisite for MATH 117: Satisfactory performance on the CSU Math Placement Tool or the ELM Exam. Place out of MATH 117 on the CSU Math Placement Tool, or complete or successfully challenge MATH 117.

In MATH 117 and MATH 118, concepts and skills traditionally identified with college algebra are presented in a learning environment that emphasizes active student involvement in investigating, interpreting, applying, and communicating mathematical ideas. Topics include linear functions, quadratic functions and equations, polynomials and polynomial equations, piecewise functions, inequalities, linear systems, rational and radical functions, inverse functions, and fractional exponents.

A Texas Instruments TI-83® or TI-84® Graphing Calculator is required. Students who are not familiar with the TI-83® or TI-84® may check out a calculator and manual from the Resource Desk to practice within the Precalculus Center.

#### MATH 124 Logarithmic and Exponential Functions

Prerequisite for MATH 124: Place out of both MATH 117 and MATH 118 on the CSU Math Placement Tool or Complete or successfully challenge each of MATH 117 and MATH 118, or An equivalent combination of placement and course challenge/completion.

The topics in this course include definitions and graphs of exponential functions, definition of the logarithmic functions as the inverses of the exponential functions, properties of logarithmic functions, techniques for solving exponential and logarithmic equations, and mathematical models involving logarithmic or exponential functions.

#### MATH 125 and MATH 126 Numerical and Analytic Trigonometry

Prerequisite for MATH 125: Place out of both MATH 117 and MATH 118 on the CSU Math Placement Tool or Complete or successfully challenge each of MATH 117 and MATH 118, or An equivalent combination of placement and course completion. Place out of MATH 125 on the CSU Math Placement Tool or Complete or successfully challenge MATH 125.

This sequence of two courses is designed to help students acquire conceptual understanding and computational proficiency with traditional topics from plane trigonometry. Content includes definitions and graphs of the six trigonometric functions, techniques for solving right and oblique triangles, the inverse trigonometric functions, trigonometric identities, and solving trigonometric equations.
