MAT 189 - Trigonometry [SUN# MAT 1187]

3 Credits, 3 Contact Hours
3 lecture periods 0 lab periods
Continuation of MAT 151 . College-level trigonometry. Includes trigonometric functions, angle measure, graphs, identities, equations, polar coordinates, and graphing device use. May also include parametric equations, vectors, and complex numbers.

Prerequisite(s): MAT 151  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 187 , and MAT 189. A graphing device is required for this course and will be used extensively.
Gen-Ed: Meets AGEC - MATH; Meets CTE - M&S.
