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

解答

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

2

求解步骤

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

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

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

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

= 2 - 0

化简

= 2

x \to 1 lim (x^{2} - 6 x + 2)

\int \frac{( e ^{- x} )}{x} d x

\int \frac{1}{( 64 + x ^{2} ) ^{\frac{3}{2}}} d x

\int_{0}^{1} (\frac{x}{1 + x ^{2}}) d x

x y^{^{'}} + y = 55 x
