Differentiate the following function with respect to `x :` `tan^(-1)((a+x)/(1-a x))`

Explanation

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

### Step 1: Identify the function
Let:
\[ y = \tan^{-1}\left(\frac{a+x}{1-ax}\right) \]
