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

- \frac{3 x + 2}{2 x ( x + 1 )}

Solution steps

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

Simplify

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

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

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

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

Apply the chain rule:

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

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

\frac{d}{d x} (x x + 1) = \frac{3 x + 2}{2 x + 1}

= - \frac{1}{x x + 1} \cdot \frac{3 x + 2}{2 x + 1}

Simplify

- \frac{1}{x x + 1} \cdot \frac{3 x + 2}{2 x + 1} : - \frac{3 x + 2}{2 x ( x + 1 )}

= - \frac{3 x + 2}{2 x ( x + 1 )}

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

x \to 3 - lim (\frac{6 x}{x - 3})

\int sin (4 x - 7) d x

\int_{- 2}^{3} \frac{16}{x ^{4}} d x

f (x) = 6 x^{3}
