derivative of ln(sqrt((x+8/(x-8))))

Lösung

\frac{d}{d x} (ln (\frac{x + 8}{x - 8}))

- \frac{8}{( x - 8 ) ( x + 8 )}

Schritte zur Lösung

\frac{d}{d x} (ln (\frac{x + 8}{x - 8}))

Wende die Kettenregel an:

\frac{1}{\frac{x + 8}{x - 8}} \frac{d}{d x} (\frac{x + 8}{x - 8})

= \frac{1}{\frac{x + 8}{x - 8}} \frac{d}{d x} (\frac{x + 8}{x - 8})

\frac{d}{d x} (\frac{x + 8}{x - 8}) = - \frac{8}{x + 8 ( x - 8 ) ^{\frac{3}{2}}}

= \frac{1}{\frac{x + 8}{x - 8}} (- \frac{8}{x + 8 ( x - 8 ) ^{\frac{3}{2}}})

Vereinfache

\frac{1}{\frac{x + 8}{x - 8}} (- \frac{8}{x + 8 ( x - 8 ) ^{\frac{3}{2}}}) : - \frac{8}{( x - 8 ) ( x + 8 )}

= - \frac{8}{( x - 8 ) ( x + 8 )}
