(\partial)/(\partial y)(sin(y)+y,x)

解答

\frac{\partial}{\partial y} (sin (y) + y, x)

cos (y) + (, x \cdot 1)

求解步骤

\frac{\partial}{\partial y} (sin (y) + y, x)

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} (sin (y)) + \frac{\partial}{\partial y} (y, x)

\frac{\partial}{\partial y} (sin (y)) = cos (y)

\frac{\partial}{\partial y} (y, x) = (, x \cdot 1)

= cos (y) + (, x \cdot 1)

\int_{0}^{2} t e^{t} d t

a re a sin^{2} (x), sin^{3} (x), 0, π

\int 3 sin (x) + 2 - 3 e^{x} d x

a re a f (x) = 4 x (1 - x), g (x) = 4 x - 4

\frac{d}{d x} (5 x + \frac{100}{x})
