Solving Trigonometric Equations with the Quadratic Formula – Trigonometry

This video focuses on solving a trigonometric equation with the quadratic formula. In addition, this video covers concepts such as the double angle identity, reference angles, coterminal angles, angles in standard position, and inverse trigonometric functions. The problem solved in this video is arguably the most challenging problem in high school trigonometry.

This video is appropriate for a student taking a course in Algebra 2/Trigonometry. Students preparing for the NY Algebra 2/Trigonometry Regents or some other Algebra 2/Trigonometry standardized state test should find this video helpful.
