(\partial)/(\partial x)(7x-3y+4)

解答

\frac{\partial}{\partial x} (7 x - 3 y + 4)

7

求解步骤

\frac{\partial}{\partial x} (7 x - 3 y + 4)

将

y

视为常数

使用微分加减法定则:

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

= \frac{\partial}{\partial x} (7 x) - \frac{\partial}{\partial x} (3 y) + \frac{\partial}{\partial x} (4)

\frac{\partial}{\partial x} (7 x) = 7

\frac{\partial}{\partial x} (3 y) = 0

\frac{\partial}{\partial x} (4) = 0

= 7 - 0 + 0

化简

= 7

\int_{0}^{1} x^{6} - x d x

y^{^{'}} + y \cdot cos (x) = sin (x) \cdot cos (x)
