Homework Help: Limits of a fourier integral

  1. Dec 6, 2011 #1
    1. The problem statement, all variables and given/known data

    3. The attempt at a solution

    When I do the integral of this function I'm unsure of what the limits are. Anyone care to help? Thanks

    I'd use latex but it's just quicker this way...

    Well f(x)=0 for [itex]x\leq 0[/itex], so the part of the integral from [itex]-\infty[/itex] to 0 vanishes, right??

    So that would leave us with?

    Oh I get ya, so the lower limit is 0 and the upper limit is [itex]-\infty[/itex]?

    I guess you mean + for the upper limit, but yeah.

    Sorry for the double post here, I mean the upper limit is [itex]\infty[/itex]
