A Trigonometric identity or trig identity is an identity that contains the trigonometric functions sine(sin), cosine(cos), tangent(tan), cotangent(cot), secant(sec), or cosecant(csc). Trigonometric identities can use to:

Simplify trigonometric expressions.

Solve trigonometric equations.

Prove that one trigonometric expression is equivalent to another so that we can replace the first expression by the second expression. The following expression can give us new insights into some applications that the first one doesn’t show.

There is an infinite number of trig identities. Only a number of are useful, the rest generally ending up as problems and exercises for college students to unravel.

Basic trigonometric identities fall into four groups:
