derivative of

f (x) = ln (x^{2} + 3)

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

Solution steps

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

Apply the chain rule:

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

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

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

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

Simplify

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

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