derivative of

\frac{1}{9 x ^{\frac{8}{9}}}

- \frac{8}{81 x ^{\frac{17}{9}}}

Solution steps

\frac{d}{d x} (\frac{1}{9 x ^{\frac{8}{9}}})

Take the constant out:

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

= \frac{1}{9} \frac{d}{d x} (\frac{1}{x ^{\frac{8}{9}}})

Apply exponent rule:

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

= \frac{1}{9} \frac{d}{d x} (x^{- \frac{8}{9}})

Apply the Power Rule:

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

= \frac{1}{9} (- \frac{8}{9} x^{- \frac{8}{9} - 1})

Simplify

\frac{1}{9} (- \frac{8}{9} x^{- \frac{8}{9} - 1}) : - \frac{8}{81 x ^{\frac{17}{9}}}

= - \frac{8}{81 x ^{\frac{17}{9}}}

\int x csc (4) x^{2} d x

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

f (x) = x^{3}

\int_{- 2}^{1} (x^{3} + 5) d x

y = x^{3} + \frac{1}{12 x}
