integral from 0 to 6.5 of 1.4*x^2+5.9

解

\int_{0}^{6.5} 1.4 \cdot x^{2} + 5.9 d x

解

166.50833 \dots

解答ステップ

\int_{0}^{6.5} 1.4 x^{2} + 5.9 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}^{6.5} 1.4 x^{2} d x + \int_{0}^{6.5} 5.9 d x

\int_{0}^{6.5} 1.4 x^{2} d x = 128.15833 \dots

\int_{0}^{6.5} 5.9 d x = 38.35

= 128.15833 \dots + 38.35

簡素化

= 166.50833 \dots
