To prove: The derivative of inverse cosine trigonometric function is
Answer to Problem 15E
The function is
Explanation of Solution
Given information:
The expression
Formula used:
Inverse cosine trigonometric function is expressed as
Calculation:
Consider inverse cosine trigonometric function.
Recall that the inverse cosine trigonometric function is expressed as
Consider the function
Differentiate both sides with respect to x ,
Recall that chain rule for differentiation is if f is a function of g then
Apply it. Also observe that y is a function of x,
Now, as value of
Recall the Pythagorean identity
Since,
Hence, it is proved that derivative of inverse cosine trigonometric function is
