Concept explainers
To calculate: The value of trigonometric expression
Answer to Problem 2E
The value of trigonometric expression
Explanation of Solution
Given information:
The trigonometric expression
Formula used:
Inverse tangent trigonometric function is expressed as
Calculation:
Consider trigonometric expression
Recall that the tangent trigonometric function is expressed as
Recall that value of tangent function at an angle
Also the angle
That is,
Take sine function to the right hand side,
Thus, the value oftrigonometric expression
To calculate: The value of trigonometric expression
