integral from 0 to 1 of (e-1)/(2e)

解答

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

\frac{e - 1}{2 e}

十进制

0.31606 \dots

求解步骤

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

常数积分:

\int a d x = a x

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

带入上下限计算后得:

\frac{e - 1}{2 e}

= \frac{e - 1}{2 e}

\int_{1}^{e} 8 x ln (x) d x

\int_{- 1}^{1} 3 x^{4} - x^{2} + x - 1 d x

\int_{0}^{4} (\frac{1}{2} x + 2) d x

\int_{2}^{4} \frac{3}{x} - \frac{6}{x ^{2}} d x

\int_{0}^{1} 2 k x d x
