integral from 2 to 3 of (3x^2+2x+3)

解

\int_{2}^{3} (3 x^{2} + 2 x + 3) d x

解

27

解答ステップ

\int_{2}^{3} 3 x^{2} + 2 x + 3 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}^{3} 3 x^{2} d x + \int_{2}^{3} 2 x d x + \int_{2}^{3} 3 d x

\int_{2}^{3} 3 x^{2} d x = 19

\int_{2}^{3} 2 x d x = 5

\int_{2}^{3} 3 d x = 3

= 19 + 5 + 3

簡素化

= 27
