To verify: The given
Explanation of Solution
Given information:
The trigonometric identity
Formula used:
Sum to product rule for trigonometric function,
Trigonometric value,
Calculation:
Consider the function,
The left hand side of equation is,
Recall that Sum to product rule for trigonometric function,
Apply it in the left hand side of the equation.
Recall trigonometric value
Apply it,
Since, left hand side and right hand side is equal, therefore, the trigonometric identity
