이상적분,improper_integral

AKA 특이적분

유한한 닫힌 구간에서만 정의되는 함수가 아니라거나
불연속인 함수라거나

또 있나?

적분 식 앞에 극한,limit을 붙여서 정의함.

극한값이 수렴converge하거나 발산diverge함.

$\int_0^1\frac1{x^p}dx=\begin{cases}\end{cases}$
$\int_1^{\infty}\frac1{x^p}dx=\begin{cases}\text{diverges} &\text{if }p\le 1\\ \text{converges to }\frac{1}{p-1}&\text{if }p>1 \end{cases}$
