(\partial)/(\partial z)(x^2+y^2z)

解答

\frac{\partial}{\partial z} (x^{2} + y^{2} z)

y^{2}

求解步骤

\frac{\partial}{\partial z} (x^{2} + y^{2} z)

将

x, y

视为常数

使用微分加减法定则:

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

= \frac{\partial}{\partial z} (x^{2}) + \frac{\partial}{\partial z} (y^{2} z)

\frac{\partial}{\partial z} (x^{2}) = 0

\frac{\partial}{\partial z} (y^{2} z) = y^{2}

= 0 + y^{2}

化简

= y^{2}
