In this video, we simplify a quadratic trigonometric function using the half angle identity in order to graph it.

This is lecture 19 (part 3/4) of the lecture series offered by Dr. Andrew Misseldine for the course Math 1060 - Trigonometry at Southern Utah University.

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.
