(\partial)/(\partial x)(zx)

解答

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

z

求解步骤

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

将

z

视为常数

将常数提出:

(a \cdot f)^{'} = a \cdot f^{'}

= z \frac{\partial}{\partial x} (x)

使用常见微分定则:

\frac{\partial}{\partial x} (x) = 1

= z \cdot 1

化简

= z

\frac{d}{d t} (sin (t) (1 - sin (t)))

\frac{d y}{d x} + 2 = x

x \to 0 lim (+ sin (x) ln (x))

x \to 0 lim (x^{2} cos (\frac{1}{2}))

\frac{d}{d x} (4 cos (x) - e^{2 x})
