In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions) are real functions which relate an angle of a right-angled triangle to ratios of two side lengths.
Learn about the six trigonometric functions: sine, cosine, tangent, cosecant, secant, and cotangent. Find out how to define them in terms of right triangles and unit circles, and how to use them to find angles and lengths.
Sep 7, 2022 · Trigonometric functions are used to model many phenomena, including sound waves, vibrations of strings, alternating electrical current, and the motion of pendulums. In fact, almost any repetitive, or cyclical, motion can be modeled by some combination of trigonometric functions.
