(\partial)/(\partial h)(1/2 (a+b)h)

解答

\frac{\partial}{\partial h} (\frac{1}{2} (a + b) h)

\frac{1}{2} (a + b)

求解步骤

\frac{\partial}{\partial h} (\frac{1}{2} (a + b) h)

将常数提出:

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

= \frac{1}{2} (a + b) \frac{\partial}{\partial h} (h)

使用常见微分定则:

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

= \frac{1}{2} (a + b) \cdot 1

化简

= \frac{1}{2} (a + b)

\frac{d}{d x} (\frac{2}{x ^{\frac{1}{3}}} - 2)

y^{^{''}} - 2 y^{^{'}} + 5 y = 5, y (0) = 2, y^{^{'}} (0) = 1

t an g e n t f (x) = (\frac{x - 3}{x + 1})^{2}, at x = 0

\int y e^{3 y} d y

\int \frac{sin ( x )}{3} d x
