derivative of

\frac{1}{r ^{3}}

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

Solution steps

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

Apply exponent rule:

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

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

Apply the Power Rule:

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

= - 3 r^{- 3 - 1}

Simplify

- 3 r^{- 3 - 1} : - \frac{3}{r ^{4}}

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

y = cos (5 x + 4)

t^{0}

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

\frac{d}{df} (f (0) + f (- 1) \cdot f (2))

y = (3 - x^{2}) (x^{3} - x + 1)
