integral from 0 to 10 of xsin(x^2)

解

\int_{0}^{10} x sin (x^{2}) d x

解

\frac{1}{2} (- cos (100) + 1)

+1

十進法表記

0.06884 \dots

解答ステップ

\int_{0}^{10} x sin (x^{2}) d x

u置換積分法を適用する

= \int_{0}^{100} \frac{sin ( u )}{2} d u

定数を除く:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{1}{2} \cdot \int_{0}^{100} sin (u) d u

共通積分を使用する:

\int sin (u) d u = - cos (u)

= \frac{1}{2} [- cos (u)]_{0}^{100}

限度を計算する:

- cos (100) + 1

= \frac{1}{2} (- cos (100) + 1)
