derivative of (ax-b/(x^2-1))

Lösung

\frac{d}{d x} (\frac{a x - b}{x ^{2} - 1})

Lösung

\frac{- a x ^{2} + 2 b x - a}{( x ^{2} - 1 ) ^{2}}

Schritte zur Lösung

\frac{d}{d x} (\frac{a x - b}{x ^{2} - 1})

Wende die Quotientenregel an:

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

= \frac{\frac{d}{d x} ( a x - b ) ( x ^{2} - 1 ) - \frac{d}{d x} ( x ^{2} - 1 ) ( a x - b )}{( x ^{2} - 1 ) ^{2}}

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

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

= \frac{a ( x ^{2} - 1 ) - 2 x ( a x - b )}{( x ^{2} - 1 ) ^{2}}

a (x^{2} - 1) - 2 x (a x - b) : - a x^{2} + 2 b x - a

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