Trigonometric Functions

With careful attention to branch cuts, the Wolfram Language supports trigonometric functions everywhere in the complex plane, with extensive exact and algebraic transformations, together with efficient arbitrary-precision numerical evaluation. The Wolfram Language follows the standard mathematical convention of using radians for trigonometric function arguments.
