derivative of ln(sqrt(x^2+12))

Solution

\frac{d}{d x} (ln (x^{2} + 12))

Solution

\frac{x}{x ^{2} + 12}

Solution steps

\frac{d}{d x} (ln (x^{2} + 12))

Apply the chain rule:

\frac{1}{x ^{2} + 12} \frac{d}{d x} (x^{2} + 12)

= \frac{1}{x ^{2} + 12} \frac{d}{d x} (x^{2} + 12)

\frac{d}{d x} (x^{2} + 12) = \frac{x}{x ^{2} + 12}

= \frac{1}{x ^{2} + 12} \cdot \frac{x}{x ^{2} + 12}

Simplify

\frac{1}{x ^{2} + 12} \cdot \frac{x}{x ^{2} + 12} : \frac{x}{x ^{2} + 12}

= \frac{x}{x ^{2} + 12}
