The course objective is to provide a working knowledge of concepts and applications of equation solutions, graphs, and trigonometry. It begins with a review of algebraic basics. Emphasis is on linear, polynomial, exponential, logarithmic, and trigonometric functions and their graphs. Students will model scenarios with all of these functions and with graphs. They will also use trigonometric identities to simplify expressions. Other topics include series and sequences, systems of equations, and matrices.
