derivative of (kx+a/(bx+c))

Lösung

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

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

Schritte zur Lösung

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

Wende die Quotientenregel an:

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

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

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

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

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