Hint:The given function is a composite function that is a function that consists of another function or the argument of a function is another function. Composite functions can be differentiated with the help of chain rule, let us take an example of a composite function , its derivative will be given as follows:
Formula used:
Chain rule: If a function is composition of various function as follows then
Derivative of logarithm function:
And derivative of tangent function:
Complete step by step answer:
In order to find the derivative of the function , we have to use chain rule because this is a composite function, tangent function is the argument of the logarithmic function in this given composite function. Let us understand chain rule in order to solve this problem.If a function is composition of various function as follows
then its derivative will be given as
In the given function
Taking derivative both sides with respect to
Now applying chain rule to the given function , we will get
We know that,
So simplifying the derivatives further with help of this,
You can left it like this or should simplify it further in sine and cosine as follows
Therefore the desired derivative of is equal to .
Note: When applying the chain rule in a more complex composite function then do the calculations or simplification stepwise, because chain rule also becomes complex for complex composite functions and your one mistake will change the whole answer.
