derivative y=4x^2+2

解答

导数

y = 4 x^{2} + 2

8 x

求解步骤

\frac{d}{d x} (4 x^{2} + 2)

使用微分加减法定则:

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

= \frac{d}{d x} (4 x^{2}) + \frac{d}{d x} (2)

\frac{d}{d x} (4 x^{2}) = 8 x

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

= 8 x + 0

化简

= 8 x

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

d er i v a t i v e 1 2^{9 x}

x \to 2 lim (\frac{x - 2}{∣ x - 2 ∣})

\int sin (2 x) e^{(3 x)} d x

y \to 0 lim (\frac{0}{y ^{2}})
