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

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

Solution steps

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

Take the constant out:

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

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

Apply exponent rule:

\frac{1}{a} = a^{- 1}

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

Apply the chain rule:

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

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

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

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

Simplify

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

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

\int \frac{8}{x ( ln ( x ) + 1 ) ^{\frac{3}{2}}} d x

3 x - 4

\int sin (t - s) d s

\frac{5}{4 - x}, at x = - 3

\int \frac{1}{- x ^{2} + 10 x} d x
