In Trigonometric Identities we will introduce the tools available to you when working with problems involving trigonometric functions. From Opposite Angle Identities to the Pythagorean Theorem of Sine and Cosine, you will be equipped to simplify and rewrite trigonometric equations. By studying different Trigonometric Techniques, such as Decomposing Angles Using Division, or Rewriting an Identity in Terms of a Ratio, you will have no trouble Solving a Pythagorean Identity for Tangent and more.
