Homework Help: Laplace transform

  1. Oct 25, 2008 #1
    G(S)=2/s(e^-3s_e^-4s)

    G(S)=(2S+1/S^2)*e^-2s_(3s+1/s^2)*e-3s


    find g(t)????

    First off, what work have you already done?
    Second, what operation does '_' represent in e^-3s_e^-4s? If it's multiplication, you can write it as (e^(-3s)*e^(-4s))
    Third, without parentheses, it's difficult to tell what's in the numerator of a rational expression, and what's in the denominator. E.g., does (2S + 1/S^2) in your second problem mean
    [tex]2S + \frac{1}{S^2}[/tex]
    or
    [tex]\frac{2S + 1}{S^2}[/tex]?
