Trigonometry

Sine, cosine, and related functions, with results in radians or degrees

The trigonometric functions in MATLAB® calculate standard trigonometric values in radians or degrees, hyperbolic trigonometric values in radians, and inverse variants of each function. You can use the rad2deg and deg2rad functions to convert between radians and degrees, or functions like cart2pol to convert between coordinate systems.
