(\partial)/(\partial u)(2usin(v))

解答

\frac{\partial}{\partial u} (2 u sin (v))

2 sin (v)

求解步骤

\frac{\partial}{\partial u} (2 u sin (v))

将

v

视为常数

将常数提出:

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

= 2 sin (v) \frac{\partial}{\partial u} (u)

使用常见微分定则:

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

= 2 sin (v) \cdot 1

化简

= 2 sin (v)

t an g e n t f (x) = x^{2} - 9, (- 4, 7)

\frac{d}{d x} (\frac{x ^{2}}{7 + x})

\int_{- \infty}^{0} \frac{1}{2 - 4 x} d x

\int_{a}^{b} f (x) d x

(ln (\frac{x}{4}))^{^{'}}
