로그 적분 함수에서 적분구간을 0으로 할때도 있고 2로 할때도 있다던데 그렇게 해도 결과적으로 값은 같게 나오나요? 계산기 돌리니깐 0으로 하면 자꾸 적분 안된다고 하던데ㅣ.........

$\mu$ 이하로 떨어지면 함숫값이 음수면서 1 제외하면 모두 정의되니까 0부터 적분하면 2부터 적분한 값 보다 더 작아지지 않을까요?

로그 적분함수는 책에서만 잠깐 보고 넘겨서 잘 모르겠네요ㅠㅠ

  그러니까요......어째서 적분 구간이 바뀌어도 값이 같을 수가 있는지.....

  @Scubed
  
  아니면 $\mu$ 가 1.5 정도이고 2가 아님을 봐서
  
  $[0,\mu]$ 의 적분값이 $[\mu,2]$ 에 근사한다고 생각할 수도 있을 것 같아요
  
  맞는지는 잘 모르겠습니다ㅠㅠ
