Hint:
We are given a function. We have to find the second derivative and first derivative of the function. Then we have to substitute the value in the given equation. We have to find the value of equation.
The correct answer is: 0
The given function is

We have to find the value of

We will simplify the given function before finding the derivative.
We will substitute ax = tanA in the given function.
So, the function becomes

Now we will take first derivative

Taking the second derivative

We will substitute the value.

So, the final answer is 0
For such questions, we should know different trigonometric formulas. We should simplify the function first before finding derivatives.
