integral from 0 to infinity of 5/(x^3)

解答

\int_{0}^{\infty} \frac{5}{x ^{3}} d x

发散

求解步骤

\int_{0}^{\infty} \frac{5}{x ^{3}} d x

计算不定积分:

\int \frac{5}{x ^{3}} d x = - \frac{5}{2 x ^{2}} + C

带入上下限计算后得:

\int_{0}^{\infty} \frac{5}{x ^{3}} d x =

发散

= 发散

t an g e n t 0 = x^{2} - x y + 2 y - 2, at x = - 2

\frac{\partial}{\partial x} (x^{3} \cdot y^{2} + 4 x^{2} - 3 x y)

x \to \infty lim (x - {x})

\int 2 yz d y

x \to 0 lim (\frac{( 2 + x ) ^{2} - 8}{x})
