Concept explainers
To verify: The given
Explanation of Solution
Given information:
The trigonometric identity
Formula used:
Sum to product rule for trigonometric function,
Conversion rules,
Calculation:
Consider the function,
First, verify the identity
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 conversion rule,
Apply it,
Therefore, the identity
Next, verify the identity
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 conversion rule,
Apply it,
Therefore, the identity
Since, left hand side and right hand side is equal, therefore, the trigonometric identity
