d/(ds)(s/(s^2+w^2))

Lösung

\frac{d}{d s} (\frac{s}{s ^{2} + w ^{2}})

Lösung

\frac{w ^{2} - s ^{2}}{( s ^{2} + w ^{2} ) ^{2}}

Schritte zur Lösung

\frac{d}{d s} (\frac{s}{s ^{2} + w ^{2}})

Behandle

w

als Konstante

Wende die Quotientenregel an:

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

= \frac{\frac{d s}{d s} ( s ^{2} + w ^{2} ) - \frac{d}{d s} ( s ^{2} + w ^{2} ) s}{( s ^{2} + w ^{2} ) ^{2}}

\frac{d s}{d s} = 1

\frac{d}{d s} (s^{2} + w^{2}) = 2 s

= \frac{1 \cdot ( s ^{2} + w ^{2} ) - 2 ss}{( s ^{2} + w ^{2} ) ^{2}}

1 \cdot (s^{2} + w^{2}) - 2 ss = w^{2} - s^{2}

= \frac{w ^{2} - s ^{2}}{( s ^{2} + w ^{2} ) ^{2}}
