Differentiate `(e^(x)+cot x)/(tan x-x^(n))` with respect to 'x'.

Explanation

To differentiate the function \( y = \frac{e^x + \cot x}{\tan x - x^n} \) with respect to \( x \), we will use the quotient rule of differentiation.

### Step-by-Step Solution:

1. **Identify the function**:
Let \( u = e^x + \cot x \) and \( v = \tan x - x^n \).

2. **Apply the Quotient Rule**:
