derivative f(x)=3x+8

解答

导数

f (x) = 3 x + 8

3

求解步骤

\frac{d}{d x} (3 x + 8)

使用微分加减法定则:

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

= \frac{d}{d x} (3 x) + \frac{d}{d x} (8)

\frac{d}{d x} (3 x) = 3

\frac{d}{d x} (8) = 0

= 3 + 0

化简

= 3

n = 0 \sum \infty ln (\frac{1}{3 ^{n}})

\int_{\frac{1}{3}}^{7} 16 x ln (3 x) d x

\frac{\partial}{\partial x} (arcsin (- 2 x^{4}))

n \to 0 lim (\frac{sin ( n )}{n})

\frac{d y}{d x} = \frac{y}{x} + \frac{y ^{2}}{x ^{2}}
