In this video, I focus on solving double angle formulas in order to solve trig equations.
This is an essential skill to learn in order to do well in pre-calculus and later in calculus.
I go through several example problems.
This video goes with following Math Standard: Prove and apply trigonometric identities.
Prove addition, subtraction, double and half-angle formulas for sine, cosine, and tangent and use them to solve problems.
