To show: The function

Answer to Problem 42E
Explanation of Solution
Given information:
The function
Formula used:
A function f is said to be one-one function if it is an increasing function and defined on real numbers.
Consider the function
Differentiate both sides with respect to x ,
Recall that range of sine trigonometric function is
The derivative of the function is positive, so the function is an increasing function.
Recall that a function f is said to be one-one function if it is an increasing function and defined on real numbers.
Since, the function
Hence, it is proved that thefunction
