derivative of 8x^3-2x

解答

\frac{d}{d x} (8 x^{3} - 2 x)

24 x^{2} - 2

求解步骤

\frac{d}{d x} (8 x^{3} - 2 x)

使用微分加减法定则:

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

= \frac{d}{d x} (8 x^{3}) - \frac{d}{d x} (2 x)

\frac{d}{d x} (8 x^{3}) = 24 x^{2}

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

= 24 x^{2} - 2

x \to + 1000 lim (18 π^{2})

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

\int (tan (5 x) + csc^{3} (3 θ)) d θ

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