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

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

Solution steps

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

Apply the Quotient Rule:

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

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

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

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

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

Simplify

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

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

k = 1 \sum \infty sin (kπ)

\int \frac{4 x - 11}{( 2 x - 1 ) ( x + 4 )} d x

\frac{d}{d x} (6 x^{2} + 5 x - 6)

\int \frac{1}{4} x d x

\frac{( 6 s + 3 )}{s ^{2}}
