Homework Help: Laplace transformation of f(t) = e^(at)

  1. Dec 24, 2005 #1
    for this question:
    f(t)=e^(at), when t>0, a is constant. find the laplace transformation.

    my question:
    for the integration part, what happens if s-a<0?

    If s < a then the integral diverges. There are conditions on f(t) for the existence of the transform.
