To find the derivative of the function
, we can use the chain rule.The chain rule states that if we have a composite function
, then the derivative of
with respect to
is given by:
In this case, we have
, which can be written as
, where
.Now, let's find the derivative of
with respect to
:
Therefore, the derivative of
is:
So, the correct answer is
.
