integral from 0 to 2 of (1-x)e^{2x}

解

\int_{0}^{2} (1 - x) e^{2 x} d x

解

\frac{- e ^{4} - 3}{4}

+1

十進法表記

- 14.39953 \dots

解答ステップ

\int_{0}^{2} (1 - x) e^{2 x} d x

部分積分を適用する

= [\frac{1}{2} e^{2 x} (1 - x) - \int - \frac{1}{2} e^{2 x} d x]_{0}^{2}

\int - \frac{1}{2} e^{2 x} d x = - \frac{1}{4} e^{2 x}

= [\frac{1}{2} e^{2 x} (1 - x) - (- \frac{1}{4} e^{2 x})]_{0}^{2}

簡素化

[\frac{1}{2} e^{2 x} (1 - x) - (- \frac{1}{4} e^{2 x})]_{0}^{2} : [\frac{1}{4} (- 2 e^{2 x} x + 3 e^{2 x})]_{0}^{2}

= [\frac{1}{4} (- 2 e^{2 x} x + 3 e^{2 x})]_{0}^{2}

限度を計算する:

- \frac{e ^{4}}{4} - \frac{3}{4}

= - \frac{e ^{4}}{4} - \frac{3}{4}

簡素化

= \frac{- e ^{4} - 3}{4}
