Expert Solution

Step 1: explainig what is trignometric identity , giving examples

A trigonometric identity is an equation that relates the trigonometric functions of one or more angles. Trigonometric identities are always true, regardless of the values of the angles involved.

Trigonometric identities are useful for a variety of reasons. They can be used to simplify trigonometric expressions, to prove other trigonometric theorems, and to solve trigonometric equations.

Here are some examples of trigonometric identities:

Pythagorean identity: $s i n squared left parenthesis x right parenthesis plus c o s squared left parenthesis x right parenthesis equals 1$
Angle addition formula: sin(a + b) = $sin left parenthesis a right parenthesis cos left parenthesis b right parenthesis space plus space cos left parenthesis a right parenthesis sin left parenthesis b right parenthesis$
