derivative of x/(5+x^2)

Solution

derivative of

\frac{x}{5 + x ^{2}}

Solution

\frac{5 - x ^{2}}{( 5 + x ^{2} ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{x}{5 + x ^{2}})

Apply the Quotient Rule:

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

= \frac{\frac{d x}{d x} ( 5 + x ^{2} ) - \frac{d}{d x} ( 5 + x ^{2} ) x}{( 5 + x ^{2} ) ^{2}}

\frac{d x}{d x} = 1

\frac{d}{d x} (5 + x^{2}) = 2 x

= \frac{1 \cdot ( 5 + x ^{2} ) - 2 xx}{( 5 + x ^{2} ) ^{2}}

1 \cdot (5 + x^{2}) - 2 xx = 5 - x^{2}

= \frac{5 - x ^{2}}{( 5 + x ^{2} ) ^{2}}
