derivative of ({r}(x)/x)

Lösung

\frac{d}{d x} (\frac{r ( x )}{x})

Lösung

\frac{x \frac{d}{d x} ( r ( x ) ) - r ( x )}{x ^{2}}

Schritte zur Lösung

\frac{d}{d x} (\frac{r ( x )}{x})

Wende die Quotientenregel an:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

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

\frac{d x}{d x} = 1

= \frac{\frac{d}{d x} ( r ( x ) ) x - 1 \cdot r ( x )}{x ^{2}}

Vereinfache

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