derivative of

\frac{2}{7 x ^{2}}

- \frac{4}{7 x ^{3}}

Solution steps

\frac{d}{d x} (\frac{2}{7 x ^{2}})

Take the constant out:

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

= \frac{2}{7} \frac{d}{d x} (\frac{1}{x ^{2}})

Apply exponent rule:

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

= \frac{2}{7} \frac{d}{d x} (x^{- 2})

Apply the Power Rule:

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

= \frac{2}{7} (- 2 x^{- 2 - 1})

Simplify

\frac{2}{7} (- 2 x^{- 2 - 1}) : - \frac{4}{7 x ^{3}}

= - \frac{4}{7 x ^{3}}

\int \frac{( x ^{2} + 2 x + 3 )}{( x ^{3} + 3 x ^{2} + 9 x )} d x

\frac{d}{d y} (3 x y)

x \to 0 lim ((1 - 3 x)^{\frac{3}{x}})

\int_{0}^{2 π} sin^{2} (4 x) d x

y = \frac{6}{x}, (4, \frac{6}{2})
