derivative of 1/10 x-1/4

解答

\frac{d}{d x} (\frac{1}{10} x - \frac{1}{4})

\frac{1}{10}

十进制

0.1

求解步骤

\frac{d}{d x} (\frac{1}{10} x - \frac{1}{4})

化简

\frac{1}{10} x - \frac{1}{4} : \frac{x}{10} - \frac{1}{4}

= \frac{d}{d x} (\frac{x}{10} - \frac{1}{4})

使用微分加减法定则:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{d}{d x} (\frac{x}{10}) - \frac{d}{d x} (\frac{1}{4})

\frac{d}{d x} (\frac{x}{10}) = \frac{1}{10}

\frac{d}{d x} (\frac{1}{4}) = 0

= \frac{1}{10} - 0

化简

= \frac{1}{10}
