Detail solution
-
Let .
-
Apply the power rule: goes to
-
Then, apply the chain rule. Multiply by :
-
The derivative of a constant times a function is the constant times the derivative of the function.
-
Apply the power rule: goes to
So, the result is:
The result of the chain rule is:
The answer is:
The first derivative
