derivative ln(sqrt(x^2-7))

解

導関数

ln (x^{2} - 7)

解

\frac{x}{x ^{2} - 7}

解答ステップ

\frac{d}{d x} (ln (x^{2} - 7))

連鎖法則を適用:

\frac{1}{x ^{2} - 7} \frac{d}{d x} (x^{2} - 7)

= \frac{1}{x ^{2} - 7} \frac{d}{d x} (x^{2} - 7)

\frac{d}{d x} (x^{2} - 7) = \frac{x}{x ^{2} - 7}

= \frac{1}{x ^{2} - 7} \cdot \frac{x}{x ^{2} - 7}

簡素化

\frac{1}{x ^{2} - 7} \cdot \frac{x}{x ^{2} - 7} : \frac{x}{x ^{2} - 7}

= \frac{x}{x ^{2} - 7}
