derivative of

9 x^{- 2}

- \frac{18}{x ^{3}}

Solution steps

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

Take the constant out:

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

= 9 \frac{d}{d x} (x^{- 2})

Apply the Power Rule:

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

= 9 (- 2 x^{- 2 - 1})

Simplify

9 (- 2 x^{- 2 - 1}) : - \frac{18}{x ^{3}}

= - \frac{18}{x ^{3}}

y = \frac{x}{1 - ln ( x - 5 )}

\int \frac{x ^{3}}{( x ^{2} - 1 ) ^{3}} d x

\int \frac{1}{x x ^{2} + 3} d x

\frac{d}{d x} (\frac{x cos ( x ) + π}{x - π})

x \to 4 lim (7 x + 12 x)
