In Trigonometric Identities we will introduce the tools available to you when working with problems involving trigonometric functions. From Angle Sum Identities to the Pythagorean Theorem of Cotangent and Cosecant, you will be equipped to simplify and rewrite trigonometric equations. Learn how to apply Ratio Identities in Rewriting an Identity in Terms of a Ratio and more. From basic concepts such as Simplifying Through Reciprocals to more complex functions such as Decomposing Angles Using Multiplication, Trigonomic Identities provides a wide range of techniques, skills and methods to elevate your level of mastery.
