MAT 189  Precalculus II [SUN# MAT 1187] 3 Credits, 3 Contact Hours 3 lecture periods 0 lab periods
Continuation of MAT 188 . Collegelevel trigonometry. Includes trigonometric functions, angle measure, graphs, identities, equations, polar coordinates, conic sections, and calculator use. May also include parametric equations, vectors, and complex numbers.
Prerequisite(s): Within the last three years: MAT 188 with a grade of C or better, or required score on the mathematics assessment test. Recommendation: This course is intended as an intensive preparation for students who plan to continue with Calculus. Information: No more than 7 credits may be applied toward graduation from the following list of courses: MAT 151 , MAT 188 , and MAT 189. A graphing calculator is required for this course and will be used extensively. GenEd: Meets AGEC  MATH; Meets CTE  M&S.
