Our online Precalculus course provides you with a working knowledge of Precalculus and its applications. Beginning with a review of algebraic operations, an emphasis is put on solving and graphing equations that involve linear, polynomial, exponential, and logarithmic functions. Throughout Precalculus, you will also learn to graph trigonometric and inverse trigonometric functions and how to use the family of trigonometric identities.
