integral from 1 to 9 of (x^2+2)

解

\int_{1}^{9} (x^{2} + 2) d x

解

\frac{776}{3}

+1

十進法表記

258.66666 \dots

解答ステップ

\int_{1}^{9} x^{2} + 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_{1}^{9} x^{2} d x + \int_{1}^{9} 2 d x

\int_{1}^{9} x^{2} d x = \frac{728}{3}

\int_{1}^{9} 2 d x = 16

= \frac{728}{3} + 16

簡素化

\frac{728}{3} + 16 : \frac{776}{3}

= \frac{776}{3}
