derivative of

- \frac{5}{x}

\frac{5}{x ^{2}}

Solution steps

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

Take the constant out:

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

= - 5 \frac{d}{d x} (\frac{1}{x})

Apply exponent rule:

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

= - 5 \frac{d}{d x} (x^{- 1})

Apply the Power Rule:

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

= - 5 (- 1 \cdot x^{- 1 - 1})

Simplify

- 5 (- 1 \cdot x^{- 1 - 1}) : \frac{5}{x ^{2}}

= \frac{5}{x ^{2}}

x, x^{2}, [0, 1]

x \to \infty lim (x \cdot 3)

x + y = 5

\int 2 sin (x) - cos (x) d x

\frac{\partial}{\partial x} (\frac{x ^{2}}{2 y} + \frac{3 y ^{2}}{x ^{2}})
