derivative of

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

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

Solution steps

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

Apply the chain rule:

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

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

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

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

Simplify

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

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

f (x) = \frac{3 x - 1}{x ^{2} + 1}, at x = 6

\int_{1}^{2} \frac{4 x ^{2} - 7 x - 12}{x ( x + 2 ) ( x - 3 )} d x

\frac{d}{d x} (x^{- \frac{3}{5}})

y = ln (x^{2} + 5)

\int \frac{1}{x x ^{2} - 16} d x
