    simple Laplace transform


    Hi guys, could you help me solve this simple problem,
    what happens is that I have a little doubt with the defining intervals of the function, thanks

    Find the
    Laplace transform of the given function

    g(t) = 0 t < 3
    = t t
    ≥ 3

    Hi frankitm!

    The Laplace transform is:

    F(s) = \mathcal{L} \left\{f(t)\right\}(s)=\int_0^{\infty} e^{-st} g(t) \,dt

    Can you fill in your g(t)?
