derivative of

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

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

Solution steps

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

Take the constant out:

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

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

Apply exponent rule:

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

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

Apply the Power Rule:

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

= - (- 3 x^{- 3 - 1})

Simplify

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

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

\int_{- \infty}^{0} e^{- 3 x} d x

x^{3} + 2 x + 1, 2

y^{^{''}} + 64 y = 0, y (0) = 1, y^{^{'}} (0) = 5

\frac{d}{d x} (- x^{3} e^{x})

\frac{\partial}{\partial x} (x e^{(x^{2} - y)})
