integral from-2 to 2 of x^2+2x

解

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

解

\frac{16}{3}

+1

十進法表記

5.33333 \dots

解答ステップ

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

\int_{- 2}^{2} x^{2} d x = \frac{16}{3}

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

= \frac{16}{3} + 0

簡素化

= \frac{16}{3}
