(\partial)/(\partial y)(5x^2-2y)

解答

\frac{\partial}{\partial y} (5 x^{2} - 2 y)

- 2

求解步骤

\frac{\partial}{\partial y} (5 x^{2} - 2 y)

将

x

视为常数

使用微分加减法定则:

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

= \frac{\partial}{\partial y} (5 x^{2}) - \frac{\partial}{\partial y} (2 y)

\frac{\partial}{\partial y} (5 x^{2}) = 0

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

= 0 - 2

化简

= - 2

n = 1 \sum \infty \frac{9}{n ln ( 2 n )}

\frac{\partial}{\partial y} (4 y sin (x^{2} y))

\int_{2}^{9} \frac{2}{( 1 - x ) ^{\frac{2}{3}}} d x
