integral from 0 to infinity of 5/(7+x)

解答

\int_{0}^{\infty} \frac{5}{7 + x} d x

发散

求解步骤

\int_{0}^{\infty} \frac{5}{7 + x} d x

计算不定积分:

\int \frac{5}{7 + x} d x = 5 ln ∣ 7 + x ∣ + C

带入上下限计算后得:

\int_{0}^{\infty} \frac{5}{7 + x} d x =

发散

= 发散

\int_{0}^{5} sin (\frac{π x}{10}) d x

\int_{- 1}^{7} \frac{1}{( x + 1 )} d x

\int_{- 5}^{6} (1 - x) d x

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

\int_{0}^{4} - x + 4 d x
