Short Question about improper integrals:

  1. Sep 12, 2007 #1

    I was Just hoping to ask a short question about improper integrals ....

    when there are two limits in the integral: the 1st limit is divergent but the second limit is indeterminate.... can it be automatically divergent? or do you need to evaluate first the second limit using LHR? so that both limits becomes divergent

    if it has 2 limits then yes both limits MUST converge.
    so if you're lucky and get the limit that diverges you can just move on to other problems quicker.
