Concept explainers
To verify: the given identity.
Explanation of Solution
Given information:
Given trigonometric identity
Calculation:
The verification of an identity is done by proving both sides of a trigonometric expression equal.
The use of trigonometric identities is vital in the transformation of the trigonometric functions. The identities to be used for the transformation are given by equation (1) and (2)
To prove the identity firstly we have to prove left hand side part of given trigonometric expression equal to right hand side part of expression using identities given by equation (1) and (2)
Since left hand side part of the expression has been proved to be equal to the right hand side part of expression. Thus identity is verified.
