(\partial)/(\partial t)(t/(2y^4))

解答

\frac{\partial}{\partial t} (\frac{t}{2 y ^{4}})

\frac{1}{2 y ^{4}}

求解步骤

\frac{\partial}{\partial t} (\frac{t}{2 y ^{4}})

将

y

视为常数

将常数提出:

(a \cdot f)^{'} = a \cdot f^{'}

= \frac{1}{2 y ^{4}} \frac{\partial}{\partial t} (t)

使用常见微分定则:

\frac{\partial}{\partial t} (t) = 1

= \frac{1}{2 y ^{4}} \cdot 1

化简

= \frac{1}{2 y ^{4}}

x \to 0 - lim (\frac{1}{2 + e ^{\frac{1}{x}}})

\int_{0}^{2} 2 x - x^{2} d x

a re a 9 x, x^{2} - 10

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