The trigonometric functions are of great importance in Physics, Astronomy, Cartography, Boating, Telecommunications, the representation of periodic phenomena, and many other applications.Ī trigonometric identity is an equality between expressions that contain trigonometric functions and is valid for all the values of the angle in which the functions are defined. They are commonly defined as ratios of two sides of a right triangle containing the angle, and can equivalently be defined as the lengths of various line segments from a unit circle. In mathematics, the trigonometric functions are functions of an angle, important when studying triangles and modeling periodic phenomena. q adjacent opposite hypotenuse adjacent cos q hypotenuse opposite tan q adjacent.
