Differentiate `tan^(-1)(secx+tanx)` , `-pi/2ltxltpi/2` with respect to `x` :

Explanation

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

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