Find the derivative of the following functions (it is to be understand 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 \( y = \frac{1 + \frac{1}{x}}{1 - \frac{1}{x}} \), we will follow these steps:

### Step 1: Rewrite the function
First, we can rewrite the function in a simpler form. We have:
\[ y = \frac{1 + \frac{1}{x}}{1 - \frac{1}{x}} \]
To combine the terms, we can find a common denominator for both the numerator and the denominator.
