integral from 0 to 3 of (6x^2+3)

解

\int_{0}^{3} (6 x^{2} + 3) d x

解

63

解答ステップ

\int_{0}^{3} 6 x^{2} + 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_{0}^{3} 6 x^{2} d x + \int_{0}^{3} 3 d x

\int_{0}^{3} 6 x^{2} d x = 54

\int_{0}^{3} 3 d x = 9

= 54 + 9

簡素化

= 63
