derivative of 2-1/x

解答

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

\frac{1}{x ^{2}}

求解步骤

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

使用微分加减法定则:

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

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

\frac{d}{d x} (2) = 0

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

= 0 - (- \frac{1}{x ^{2}})

化简

= \frac{1}{x ^{2}}

\int (\frac{1}{ln ( x )} + ln (ln (x))) d x

d er i v a t i v e f (x) = lo g_{7} (x e^{x})

\int_{0}^{1} e^{5} d x

\frac{\partial}{\partial y} (z arcsin (\frac{y}{x}))

\int (2 - t) e^{- s t} d t
