derivative of

\frac{1}{5 x ^{2}}

- \frac{2}{5 x ^{3}}

Solution steps

\frac{d}{d x} (\frac{1}{5 x ^{2}})

Take the constant out:

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

= \frac{1}{5} \frac{d}{d x} (\frac{1}{x ^{2}})

Apply exponent rule:

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

= \frac{1}{5} \frac{d}{d x} (x^{- 2})

Apply the Power Rule:

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

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

Simplify

\frac{1}{5} (- 2 x^{- 2 - 1}) : - \frac{2}{5 x ^{3}}

= - \frac{2}{5 x ^{3}}

\frac{\partial}{\partial x} (tan (3 x))

y^{^{''}} - 9 y^{^{'}} + 20 y = 0

x \to 4 lim (\frac{x - 5}{x - 4})

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

\frac{d}{d x} (\frac{x ^{4}}{4} - \frac{9}{2} x^{2} + 1)
