Special Angles

In this video, we discuss the right triangle trigonometry of the degenerate triangle 0-90-90 to compute sine and cosine of 0 degree and 90 degree angles. We add this to our list of so-called special angles, which also includes 30, 45, and 60 degree angles.

This is lecture 6 (part 3/5) of the lecture series offered by Dr. Andrew Misseldine for the course Math 1060 - Trigonometry at Southern Utah University. A transcript of this lecture can be found at Dr. Misseldine's website or through his Google Drive at: https://drive.google.com/file/d/12mIqwGqlEd9nLGWJqcGErnFjmXMeAkpp/view

This lecture is based upon general college trigonometry curriculum and not based upon an individual textbook. With that said, this lecture series is influenced by many great trigonometry textbooks on the market, namely Sullivan's, Stewart's, OpenStax's, McKeague's, Stitz-Zeager's, and many others. Please post any questions you might have below in the comment field and Dr. Misseldine (or other commenters) can answer them for you. Please also subscribe for further updates.
