derivative of

f (x) = ln (x^{3})

\frac{3}{x}

Solution steps

\frac{d}{d x} (ln (x^{3}))

Apply the chain rule:

\frac{1}{x ^{3}} \frac{d}{d x} (x^{3})

= \frac{1}{x ^{3}} \frac{d}{d x} (x^{3})

\frac{d}{d x} (x^{3}) = 3 x^{2}

= \frac{1}{x ^{3}} \cdot 3 x^{2}

Simplify

\frac{1}{x ^{3}} \cdot 3 x^{2} : \frac{3}{x}

= \frac{3}{x}

\int ∣ 2 x - 1 ∣ d x

\int \frac{1}{5 x ^{2} - 20 x + 100} d x

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

\frac{d}{d x} (\frac{2 x}{4 + x})

\int \frac{1}{4 + t ^{2}} d t
