derivative of ln((x^{1/2}/3))

解答

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

\frac{1}{2 x}

求解步骤

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

使用连锁律:

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

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

\frac{d}{d x} (\frac{x ^{\frac{1}{2}}}{3}) = \frac{1}{6 x ^{\frac{1}{2}}}

= \frac{1}{\frac{x ^{\frac{1}{2}}}{3}} \cdot \frac{1}{6 x ^{\frac{1}{2}}}

化简

\frac{1}{\frac{x ^{\frac{1}{2}}}{3}} \cdot \frac{1}{6 x ^{\frac{1}{2}}} : \frac{1}{2 x}

= \frac{1}{2 x}
