Explanation of Solution
Given information:
Given −
Calculation:
A trigonometric equation is true for only certain values of variables while a trigonometric identity is true for all values of variables. In a trigonometric equation expressions on both side of equal sign are equal while in case of trigonometric identity expression on both side of equal sign are equivalent. While verifying trigonometric identity, we do not assume that both sides are equal. Therefore, any properties of equality cannot be used for verifying.
Hence,
