d/(ds)(s/(s^2+1))

Solution

\frac{d}{d s} (\frac{s}{s ^{2} + 1})

Solution

\frac{- s ^{2} + 1}{( s ^{2} + 1 ) ^{2}}

Solution steps

\frac{d}{d s} (\frac{s}{s ^{2} + 1})

Apply the Quotient Rule:

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

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

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

\frac{d}{d s} (s^{2} + 1) = 2 s

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

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

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