\frac{d}{d x} (ln (\frac{2 x + 1}{2 x - 1}))

- \frac{4}{( 2 x + 1 ) ( 2 x - 1 )}

Solution steps

\frac{d}{d x} (ln (\frac{2 x + 1}{2 x - 1}))

Apply the chain rule:

\frac{1}{\frac{2 x + 1}{2 x - 1}} \frac{d}{d x} (\frac{2 x + 1}{2 x - 1})

= \frac{1}{\frac{2 x + 1}{2 x - 1}} \frac{d}{d x} (\frac{2 x + 1}{2 x - 1})

\frac{d}{d x} (\frac{2 x + 1}{2 x - 1}) = - \frac{4}{( 2 x - 1 ) ^{2}}

= \frac{1}{\frac{2 x + 1}{2 x - 1}} (- \frac{4}{( 2 x - 1 ) ^{2}})

Simplify

\frac{1}{\frac{2 x + 1}{2 x - 1}} (- \frac{4}{( 2 x - 1 ) ^{2}}) : - \frac{4}{( 2 x + 1 ) ( 2 x - 1 )}

= - \frac{4}{( 2 x + 1 ) ( 2 x - 1 )}
