MATH 143 Pre-Calculus Pre-calculus mathematics focuses on mathematical reasoning and solving problems to improve the mathematical skill of the student. The following topics from algebra and trigonometry are studied in depth: review of algebraic concepts, functions and graphs, conic sections, solution of systems of equations, theory of equations, sequences, series, binomial theorem, permutations and combinations, trigonometric functions and their graphs, trigonometric identities and equations, solution of triangles applications, inverse trigonometric functions. The use of graphing, calculators and computers is strongly recommended. Writing assignments, as appropriate to the discipline, are part of the course. Prerequisite: SAT Math Score of 530 or higher.
