Differentiate each function by applying the basic rules of differentiation
`((2u)/(1-2u))`

Explanation

To differentiate the function \( y = \frac{2u}{1 - 2u} \) with respect to \( u \), we will apply the quotient rule of differentiation. The quotient rule states that if you have a function in the form of \( \frac{u}{v} \), its derivative is given by:

\[ \frac{dy}{du} = \frac{v \frac{du}{du} - u \frac{dv}{du}}{v^2} \]

where \( u \) and \( v \) are functions of \( u \).
