# Trigonometry

This course provides a study of the relationships between the angles and sides of triangles, relationships between central angles and coordinate points on a circle, right triangles, circular functions, degree/radian measures of angles, trigonometric functions of angles, inverse functions, identities, graphic representations of trigonometric functions, law of sines and cosines, trigonometric equations, solutions of right and oblique triangles equations, vectors, complex numbers, and polar coordinates. Upon completion, students should be able to solve practical problems and use appropriate models for analysis. This course is designed to prepare students for further study in mathematics required in the sciences and other technical fields.
Prerequisite: Intermediate Algebra with a grade of C or better. Precalculus or College Algebra with a grade of C or better is recommended.
