MATH 0090 - Introductory Trigonometry

Credits: 2
Hours/Week: Lecture None Lab None
Course Description: This course is designed for students who have never had a course in trigonometry or who need to review trigonometry before attempting college level trigonometry. Topics include definitions of trigonometric functions, solving right triangles, laws of sines and cosines, trigonometric identities, trigonometric equations, radian measure, graphs of trigonometric functions. MATH 0090 may be taken concurrently with MATH 1061 . A graphing calculator is required. Instruction will be provided in the use of the TI-83/TI-84 calculator.
MnTC Goals

Prerequisite(s): MATH 0070  with a grade of C or higher, or assessment score placement in MATH 0090.
