\frac{d}{d x} (\frac{2}{1 - 7 x})

\frac{14}{( 1 - 7 x ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{2}{1 - 7 x})

Take the constant out:

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

= 2 \frac{d}{d x} (\frac{1}{1 - 7 x})

Apply exponent rule:

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

= 2 \frac{d}{d x} ((1 - 7 x)^{- 1})

Apply the chain rule:

- \frac{1}{( 1 - 7 x ) ^{2}} \frac{d}{d x} (1 - 7 x)

= - \frac{1}{( 1 - 7 x ) ^{2}} \frac{d}{d x} (1 - 7 x)

\frac{d}{d x} (1 - 7 x) = - 7

= 2 (- \frac{1}{( 1 - 7 x ) ^{2}} (- 7))

Simplify

2 (- \frac{1}{( 1 - 7 x ) ^{2}} (- 7)) : \frac{14}{( 1 - 7 x ) ^{2}}

= \frac{14}{( 1 - 7 x ) ^{2}}

n = 0 \sum \infty \frac{1}{n + 5}

\int \frac{x ^{2}}{( 64 - x ^{2} ) ^{\frac{3}{2}}} d x

(e^{- t} cos (t))^{^{'}}

\int 6^{x} d x

\int arcsinh (x) d x
