derivative of

ln (x^{3} + 1)

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

Solution steps

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

Apply the chain rule:

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

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

\frac{d}{d x} (x^{3} + 1) = 3 x^{2}

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

Simplify

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

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