derivative of 5x+2

解答

\frac{d}{d x} (5 x + 2)

5

求解步骤

\frac{d}{d x} (5 x + 2)

使用微分加减法定则:

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

= \frac{d}{d x} (5 x) + \frac{d}{d x} (2)

\frac{d}{d x} (5 x) = 5

\frac{d}{d x} (2) = 0

= 5 + 0

化简

= 5

\frac{\partial}{\partial x} (sin (x \cdot y \cdot e^{x^{2}}))

f^{^{'}} (x) = 2^{4 x} + 4 x^{2}

\int (1 - 2 x)^{9} d x

d er i v a t i v e e^{t} \cdot cos (2 t)

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