Mastering Trigonometry: Functions, Identities & Graphs

Review trigonometric functions, special triangles, radian measure, identities, and graphs for a comprehensive understanding. Use simple x=1 approach for evaluation and recall function positivities in quadrants. Explore reciprocal, quotient, Pythagorean identities, and double angle identity. Visualize trig functions on the unit circle, and grasp their behavior with graphs.
