Homework Help: Infinite limits

  1. Nov 6, 2006 #1
    I don't remember any rules on how to calculate limits approaching infinity.
    for example, can someone please explain the following limit to me

    (-1/2) lim (t->infinity) 1/(t^2 + 2) + 1/4 =

    0 + 1/4 = 1/4

    Thanks!

    oh I think I get it now.. as t gets bigger the function -1/2 (1/(t^2+2)) approaches 0.. therefore we set it equal to 0?

    Any feedback is much appreciated. Thanks!

    Yes, that is the correct reasoning.
