(\partial)/(\partial x)(1/i+1/o)

解答

\frac{\partial}{\partial x} (\frac{1}{i} + \frac{1}{o})

0

求解步骤

\frac{\partial}{\partial x} (\frac{1}{i} + \frac{1}{o})

化简

\frac{1}{i} + \frac{1}{o} : - i + \frac{1}{o}

= \frac{\partial}{\partial x} (- i + \frac{1}{o})

将

o

视为常数

常数微分:

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

= 0

\int_{0}^{2} (2 - x) d x

x \to 1 lim (cos (x))

\frac{d y}{d x} = \frac{y - 1 - 2 y + y + 1}{x ^{2}}

a re a y = \frac{- x ^{3}}{2} - \frac{x ^{2}}{2} + \frac{5 x}{2}, y = \frac{- x}{2}

\int (- 2 e^{3 x} + \frac{5}{x}) d x
