derivative-0.0000272x^2+0.008459x+440

解答

导数

- 0.0000272 x^{2} + 0.008459 x + 440

- 0.0000544 x + 0.008459

求解步骤

\frac{d}{d x} (- 0.0000272 x^{2} + 0.008459 x + 440)

使用微分加减法定则:

(f \pm g)^{'} = f^{'} \pm g^{'}

= - \frac{d}{d x} (0.0000272 x^{2}) + \frac{d}{d x} (0.008459 x) + \frac{d}{d x} (440)

\frac{d}{d x} (0.0000272 x^{2}) = 0.0000544 x

\frac{d}{d x} (0.008459 x) = 0.008459

\frac{d}{d x} (440) = 0

= - 0.0000544 x + 0.008459 + 0

化简

= - 0.0000544 x + 0.008459

x \to \infty lim (- \frac{4 x}{5})

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

\frac{\partial}{\partial x} (sec (x))

\int 2 x (x^{2} + 12)^{3} d x

\int (2 x + 1) e^{0.4 x} d x
