Find derivative of the following functions (it is to be understood that a, b, c, d, p, q, r and s are fixed non-zero constants and m and n are integers): `(1+1/x)/(1-1/x)`

Explanation

To find the derivative of the function \( f(x) = \frac{1 + \frac{1}{x}}{1 - \frac{1}{x}} \), we will follow these steps:

### Step 1: Rewrite the function
First, we can rewrite the function in a simpler form. We can express \( f(x) \) as:
\[ f(x) = \frac{x + 1}{x - 1} \]
This is done by multiplying the numerator and the denominator by \( x \).
