derivative h(v)=4v^2-2

解答

导数

h (v) = 4 v^{2} - 2

8 v

求解步骤

\frac{d}{d v} (4 v^{2} - 2)

使用微分加减法定则:

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

= \frac{d}{d v} (4 v^{2}) - \frac{d}{d v} (2)

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

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

= 8 v - 0

化简

= 8 v

t an g e n t f (x) = 9 x^{2} + 7 x - 6, at x = - \frac{7}{18}

\frac{d}{d x} (1 - ∣ x ∣)

\int e^{x} + cos (x) d x

\int \frac{5 x + 3}{7 x - 1} d x
