Hint: We will use different differentiation rules and formulas to solve the given question. As the given function is a composite function so we will use the chain rule to find the derivative. First we will differentiate the function by using power rule then we will use .
Complete step by step answer:
We have been given a function .
We have to find the derivative of the given function.
Now let us assume that
Now, differentiating the given function with respect to x we will get
Now, the given function is a composite function so we need to apply the chain rule.
Now, we know that
Applying the formula in the above equation we will get
Now, we know that
Applying the formula in the above-obtained equation we will get
Taking the constant term out we will get
Now, we know that
Applying the formula in the above-obtained equation we will get
Now, solving further we will get
Hence we get the derivative of as .
Note:
We can also further simplify the obtained differentiation value by using trigonometric identities and formulas. Also do not get confused between the product rule and chain rule of the differentiation. The product rule is applied when one function is multiplied by another function. We cannot directly differentiate the product of functions or a composite function.
