derivative of

\frac{1}{u}

- \frac{1}{2 u ^{\frac{3}{2}}}

Solution steps

\frac{d}{d u} (\frac{1}{u})

Apply exponent rule:

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

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

Apply the Power Rule:

\frac{d}{d x} (x^{a}) = a \cdot x^{a - 1}

= - \frac{1}{2} u^{- \frac{1}{2} - 1}

Simplify

- \frac{1}{2} u^{- \frac{1}{2} - 1} : - \frac{1}{2 u ^{\frac{3}{2}}}

= - \frac{1}{2 u ^{\frac{3}{2}}}
