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

- \frac{1}{2 7 x ^{\frac{3}{2}}}

Solution steps

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

Apply exponent rule:

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

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

Apply the chain rule:

- \frac{1}{2 ( 7 x ) ^{\frac{3}{2}}} \frac{d}{d x} (7 x)

= - \frac{1}{2 ( 7 x ) ^{\frac{3}{2}}} \frac{d}{d x} (7 x)

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

= - \frac{1}{2 ( 7 x ) ^{\frac{3}{2}}} \cdot 7

Simplify

- \frac{1}{2 ( 7 x ) ^{\frac{3}{2}}} \cdot 7 : - \frac{1}{2 7 x ^{\frac{3}{2}}}

= - \frac{1}{2 7 x ^{\frac{3}{2}}}

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

\int cos^{6} (2 x) d x

(y + 1) y^{^{'}} = x y - y

e^{a x^{3}}

\frac{d y}{d x} = e^{2 y + 8 x}
