Divergent or convergent integral - Mathematics Stack Exchange
In this case, integral diverges or converges depending on the value of limit. If $-\mu + 1 < 0 \Rightarrow \mu > 1$ limit exists and is finite, so integral converges. For all other values of $\mu$ integral diverges. So $\mu > 1$ converges $\mu \le 1$ diverges
Why are some improper integrals convergent and others divergent?
2019年8月25日 · Intuitively, Riemann integral is about summing areas of infinitely many rectangles. If these areas decrease fast enough, integral converges and otherwise it doesn't. Let me compare $\int_0^1 1/x^2\, dx$ and $\int_1^\infty 1/x^2\,dx$. Like before, consider the following

calculus - How to determine whether an improper integral …
2016年3月2日 · Hence it is convergent by comparison test. You should not extend the inequality to $\int_{9}^{\infty } \frac{1}{x}dx$ because it's divergent and a convergent integral is always less than a divergent integral, so it's of no use.
