Differentiate w.r.t x , ` y = tan^(-1) (x /(sqrt(1+x^(2))-1))`

Explanation

To differentiate the function \( y = \tan^{-1} \left( \frac{x}{\sqrt{1+x^2}-1} \right) \) with respect to \( x \), we will follow these steps:

### Step 1: Rewrite the function
We start with the function:
\[ y = \tan^{-1} \left( \frac{x}{\sqrt{1+x^2}-1} \right) \]
