Description

This course is a rigorous approach to basic Trigonometry. It sets out to show the foundations of the subject in a theoretical way. By reading a formal textbook, watching PowerPoints on each topic, and taking actual tests, students will gain a deep and thorough understanding of the necessities of the subject.

This course will teach concepts such as the sine, cosine, and tangent function, radian measure, the use of the Unit Circle, identities, and more. There are 15 lectures with almost 4 hours of content. Students will receive a full textbook (with selected answers) and have access to three tests is .pdf format.

This course has been designed to help introduce students to Trigonometry and its basic skills. High school students seeking to prepare themselves for a Pre-Calculus or year-long Trigonometry course are part of the main audience, but this course certainly can benefit others looking to review this material, or simply learn it from a more theoretical standpoint.

Who is the target audience?

- Those looking for an introduction to Trigonometry
- Those looking to relearn Trigonometry
- Those looking to learn Trigonometry properly and theoretically
- Not for those needing an entire semester-long Trigonometry course
- Not for those requiring advanced level trigonometry (concepts such as DeMoivre's Theorem, for instance)
