integral from-2 to 2 of (-7x+2)

解

\int_{- 2}^{2} (- 7 x + 2) d x

解

8

解答ステップ

\int_{- 2}^{2} - 7 x + 2 d x

総和規則を適用する:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= - \int_{- 2}^{2} 7 x d x + \int_{- 2}^{2} 2 d x

\int_{- 2}^{2} 7 x d x = 0

\int_{- 2}^{2} 2 d x = 8

= - 0 + 8

簡素化

= 8
