ln (\frac{x}{x ^{2} + c})

\frac{- x ^{2} + c}{x ( x ^{2} + c )}

Schritte zur Lösung

\frac{d}{d x} (ln (\frac{x}{x ^{2} + c}))

Wende die Kettenregel an:

\frac{1}{\frac{x}{x ^{2} + c}} \frac{d}{d x} (\frac{x}{x ^{2} + c})

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

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

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

Vereinfache

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

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