    NB: The answer at the bottom of image: j = i = \sqrt{-1}
    (Sorry, us Electronic Engineers don't do things properly - feel free to work in terms of i, I do )

    I've been working through the problems in my maths notes from a couple of lectures that I might have been fairly drunk in, and came across this one which has thrown me.

    I've done the first part, but I don't know how to use the frequency shift property for the next part :s

    It's probably something rediculously simple :<

    (Frequency shift property: if f(t) and F(W) are a Fourier Transform pair then e^{j\omega_0 t}f(t) and F(\omega - \omega_0) are also a Fourier Transform pair. )

    Can you follow my working?

    It's just some rough working to give you an idea of how the problem is solved. I'm sure that you can rigourise it.

    If you have any questions, please ask.
