\frac{d}{d x} (ln (\frac{4}{x x + 1}))

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

Solution steps

\frac{d}{d x} (ln (\frac{4}{x x + 1}))

Apply the chain rule:

\frac{1}{\frac{4}{x x + 1}} \frac{d}{d x} (\frac{4}{x x + 1})

= \frac{1}{\frac{4}{x x + 1}} \frac{d}{d x} (\frac{4}{x x + 1})

\frac{d}{d x} (\frac{4}{x x + 1}) = - \frac{2 ( 3 x + 2 )}{x ^{2} ( x + 1 ) x + 1}

= \frac{1}{\frac{4}{x x + 1}} (- \frac{2 ( 3 x + 2 )}{x ^{2} ( x + 1 ) x + 1})

Simplify

\frac{1}{\frac{4}{x x + 1}} (- \frac{2 ( 3 x + 2 )}{x ^{2} ( x + 1 ) x + 1}) : - \frac{3 x + 2}{2 x ( x + 1 )}

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

(e^{x^{2} - 1})^{^{'}}

\frac{\partial}{\partial x} (- 2 x y)

\frac{d}{d x} ((x^{3} - 4 x + 1) e^{x})

\frac{d}{d x} (arcsec^{2} (x))

x \to 0 lim (\frac{5}{tan ( 3 x )})
