derivative of

\frac{9}{x}

- \frac{9}{x ^{2}}

Solution steps

\frac{d}{d x} (\frac{9}{x})

Take the constant out:

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

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

Apply exponent rule:

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

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

Apply the Power Rule:

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

= 9 (- 1 \cdot x^{- 1 - 1})

Simplify

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

= - \frac{9}{x ^{2}}

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

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

\int x cos (\frac{1}{2} x) d x

7 \frac{d ^{2} y}{d x ^{2}} + 4 \frac{d y}{d x} + 9 y = 0
