Difference Between Trigonometric Identities and Equations
In this video, I go through the difference of trigonometric equations and trigonometric identities. I talk about what words you should look for when trying to determine whether is a trig identity or equation. I also go through what we need to remember before solving these trig equations. We need to know the CAST rule, the special triangles, the unit circle, double angle formulas, and of course trigonometric identities. If you need a refresher of any of these concepts check out the other 3 Parts to this series as well as some previous videos where I outline special triangles and the unit circle. Make sure you understand the strategy to solving trigonometric identities and trigonometric equations – its very important you know the difference!
