\frac{d}{d x} (ln (\frac{x + 1}{x - 3}))

- \frac{4}{( x + 1 ) ( x - 3 )}

Solution steps

\frac{d}{d x} (ln (\frac{x + 1}{x - 3}))

Apply the chain rule:

\frac{1}{\frac{x + 1}{x - 3}} \frac{d}{d x} (\frac{x + 1}{x - 3})

= \frac{1}{\frac{x + 1}{x - 3}} \frac{d}{d x} (\frac{x + 1}{x - 3})

\frac{d}{d x} (\frac{x + 1}{x - 3}) = - \frac{4}{( x - 3 ) ^{2}}

= \frac{1}{\frac{x + 1}{x - 3}} (- \frac{4}{( x - 3 ) ^{2}})

Simplify

\frac{1}{\frac{x + 1}{x - 3}} (- \frac{4}{( x - 3 ) ^{2}}) : - \frac{4}{( x + 1 ) ( x - 3 )}

= - \frac{4}{( x + 1 ) ( x - 3 )}
