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

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

Solution steps

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

Apply the chain rule:

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

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

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

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

Simplify

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

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

\frac{d}{d x} (sin (3 x y))

\int x^{2} 5^{x^{3}} d x

y = 4 sec (5 x)

\int_{0}^{3} \frac{1}{1 - x} d x

\frac{d}{d x} (sin (2 x + 1))
