(\partial)/(\partial y)(1+x^4+y^3)

解答

\frac{\partial}{\partial y} (1 + x^{4} + y^{3})

3 y^{2}

求解步骤

\frac{\partial}{\partial y} (1 + x^{4} + y^{3})

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} (1) + \frac{\partial}{\partial y} (x^{4}) + \frac{\partial}{\partial y} (y^{3})

\frac{\partial}{\partial y} (1) = 0

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

\frac{\partial}{\partial y} (y^{3}) = 3 y^{2}

= 0 + 0 + 3 y^{2}

化简

= 3 y^{2}

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

\frac{d}{d x} (\frac{( 1 - sec ( x ) )}{tan ( x )})

s im pl i f y x + \frac{1}{x ^{2}} + x^{3}

\int 5 e^{- 2 x} + 4 d x

6 \frac{d y}{d x} - y^{2} = 0
