To find: The composite function in the form
Answer to Problem 6E
The inner function is
The derivative of y is
Explanation of Solution
Given:
The function is
Result used:
The Chain Rule:
If h is differentiable at x and g is differentiable at
Power Rule:
If n is positive integer, then
Calculation:
Let the inner function be
Then,
Therefore,
Hence, the inner function is
Thus, the required form of composite function is
Obtain the derivative of y.
Let
Apply the chain rule as shown in equation (1),
The derivative
Apply the power rule as shown in equation (2)
Substitute
The derivative
The derivative of
Thus, the derivative of
Substitute
Therefore, the derivative of
