derivative of

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

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

Solution steps

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

Take the constant out:

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

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

Apply the Power Rule:

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

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

Simplify

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

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

2 tan (x) - 7 sec (x)

\frac{( 2 x ^{2} - 4 )}{( 3 x ^{2} + 7 )}

x = \frac{1}{t}

\frac{t ^{3}}{6}

\frac{1}{x ^{2} + y ^{2}}
