derivative of ln(sqrt((a+bx/(a-bx))))

Lösung

\frac{d}{d x} (ln (\frac{a + b x}{a - b x}))

\frac{ab}{( - b x + a ) ( b x + a )}

Schritte zur Lösung

\frac{d}{d x} (ln (\frac{a + b x}{a - b x}))

Wende die Kettenregel an:

\frac{1}{\frac{a + b x}{a - b x}} \frac{d}{d x} (\frac{a + b x}{a - b x})

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

\frac{d}{d x} (\frac{a + b x}{a - b x}) = \frac{ab}{b x + a ( - b x + a ) ^{\frac{3}{2}}}

= \frac{1}{\frac{a + b x}{a - b x}} \cdot \frac{ab}{b x + a ( - b x + a ) ^{\frac{3}{2}}}

Vereinfache

\frac{1}{\frac{a + b x}{a - b x}} \cdot \frac{ab}{b x + a ( - b x + a ) ^{\frac{3}{2}}} : \frac{ab}{( - b x + a ) ( b x + a )}

= \frac{ab}{( - b x + a ) ( b x + a )}
