# MATH 118: Precalculus II

Credit Hours

3

Prerequisites

MATH 117 with a grade of C- or higher, or Math Placement Assessment

Description

A continuation of MATH 117 focusing on exponential, logarithmic, trigonometric, and inverse trigonometric functions, their graphs, and their properties. Techniques for solving equalities involving these functions are examined. Trigonometric identities, sum and difference formulas, double and half-angle formulas, the Laws of Sines and Cosines, and polar coordinates are also considered.
