derivative of

f (x) = - \frac{2}{x ^{2}}

\frac{4}{x ^{3}}

Solution steps

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

Take the constant out:

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

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

Apply exponent rule:

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

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

Apply the Power Rule:

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

= - 2 (- 2 x^{- 2 - 1})

Simplify

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

= \frac{4}{x ^{3}}

\int sin^{3} (13 x) d x

f (x) = x^{3} + 6 x^{2} + 19 x + 15, at x = 7

y = 10 x

(3 t^{2})^{^{'}}
