\frac{d}{d x} (\frac{x}{1 + x})

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

Solution steps

\frac{d}{d x} (\frac{x}{1 + x})

Apply the Quotient Rule:

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

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

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

\frac{d}{d x} (1 + x) = 1

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

Simplify

\frac{\frac{1}{2 x} ( 1 + x ) - 1 \cdot x}{( 1 + x ) ^{2}} : \frac{1 - x}{2 x ( 1 + x ) ^{2}}

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

\int 30 (x + 5) (x + 7)^{4} d x

y^{^{'}} = x (5 - y)

y = ln (1 - x)

\frac{g ( x )}{1 + f ( x )}

x \to - 3 lim (\frac{3 x}{9 - x ^{2}})
