Course Details

This course is delivered by Westcott Courses in partnership with Brandman University

MATU 102 - Trigonometry

Prerequisite: Intermediate Algebra with a grade of C or better. Precalculus or College Algebra with a grade of C or better is recommended.

Course Description: This course provides a study of the relationships between 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, vectors, complex numbers, and polar coordinates. Upon completion, students will be able to solve practical problems and use appropriate models for analysis.

Enrollment Schedule: Enroll any day of the year, and start that same day. Students have five months of access, plus a 30 day extension at the end if needed. Students can finish the self-paced courses as soon as they are able. Most students finish the lower level courses in 4 - 8 weeks. The upper level math classes, such as Calculus and above, usually take students 3-4 months. (Note: The 30-day extension cannot take your total course time six months beyond the date of enrollment. At the end of the six months, we must post a grade with the university.)

How it Works

These individual courses are available to anyone in the public who would like to enroll in a math or general education course. Unlike traditional colleges where one must enroll in a degree granting program, Westcott Courses offers individual courses where filling out a one page form makes the course immediately available. Westcott Courses is the teacher of the course and your official transcript with academic semester credits will come from one of our partner universities which are regionally accredited by WASC. Westcott Courses does not appear on the transcript; the transcript will show our courses the same way it would show a traditional class taken on the universities campus without being enrolled as a regular student. View transferring the credits.

Teachers for the Course

The classes are self-paced; however, a teacher is attached to each course who holds at least a master's degree in their field of study (or related). Most of our teachers are teachers who teach the exact same course on either a California State University or California Community college campus.

Omega MathTM Courses

Courses that have the trademark of "Omega MathTM Courses", are courses that have been written by our Omega Math team, and have a format that students love! These courses contain all the lessons, homework, solution manuals, quizzes, tests and the final. Students can take each test and quiz twice, and only the higher of the two scores counts towards their grade. This feature enables students to figure out what they did wrong before pushing forward, providing them with a deeper understanding of the course material.
