Simple question about Integral Test

  1. May 15, 2008 #1
    Hi all,
    I just want to know a little something:
    When doing the integral test in order to find a sum, when might get a result (integral) of a certain number. As we know, getting a number as result an integral test means that this serie converges...but does that mean that the serie converges to this (the result of the integral...number we just found)?
    I don't think so, but I'm not sure either.

    Thanks for the info

    No it does not.

    Thanks for the fast reply dude!

    If that number is not the sum, does it represent something?
    (just outta curiosity)
    Thank you

    It is a first approximations of the sum.
    For example say we desired to know
    other integrals can be used for better approximations
