    Hi there,
    I'm stuck on this problem:
    Given that the Fourier Transform of e^(α|t|) is

    2α/(α^2 + ω^2),

    determine the Fourier transform of

    5/(t^2 + α^2).
    I have no idea where to start :( Please help!

    There, a is constant, u can use property f(t)---->F(w)
    then F(t)----->2*pi*f(-w).
