Trigonometric Identities are the equalities that involve trigonometry functions and holds true for all the values of variables given in the equation. There are various distinct trigonometric identities involving the side length as well as the angle of a triangle. The trigonometric identities hold true only for the right-angle triangle.
The Six Basic Trigonometric Functions. Trigonometric functions allow us to use angle measures, in radians or degrees, to find the coordinates of a point on any circle—not only on a unit circle—or to find an angle given a point on a circle. They also define the relationship between the sides and angles of a triangle.
Trigonometric Identities are various identities that are used to simplify various complex equations involving trigonometric functions. Trigonometry is a branch of Mathematics that deals with the relationship between the sides and angles of a triangle., These relationships are defined in the form of six ratios which are called trigonometric ratios - sin, cos, tan, cot, sec, and cosec.

We will begin with the Pythagorean Identities (see Table 1 ), which are equations involving trigonometric functions based on the properties of a right triangle.
When applied to an angle, trigonometric functions return the ratio of the sides of a right triangle. So, in contrast, inverse trigonometric functions return the angle between two sides of a right triangle when they are applied to the ratio of these sides.
