Lösung

\frac{d}{d x} (\frac{a + b x}{c + d x})

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

Schritte zur Lösung

\frac{d}{d x} (\frac{a + b x}{c + d x})

Wende die Quotientenregel an:

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

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

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

\frac{d}{d x} (c + d x) = d

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