derivative of

f (r) = \frac{5}{r ^{3}}

- \frac{15}{r ^{4}}

Solution steps

\frac{d}{d r} (\frac{5}{r ^{3}})

Take the constant out:

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

= 5 \frac{d}{d r} (\frac{1}{r ^{3}})

Apply exponent rule:

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

= 5 \frac{d}{d r} (r^{- 3})

Apply the Power Rule:

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

= 5 (- 3 r^{- 3 - 1})

Simplify

5 (- 3 r^{- 3 - 1}) : - \frac{15}{r ^{4}}

= - \frac{15}{r ^{4}}

\frac{d}{d x} (2 x y + y)

\frac{\partial}{\partial t} (s t)

f (x) = \frac{x ^{2}}{4 - x ^{2}}

\int cos^{5} (x s i) n^{4} x
