Hi there,
I'm having trouble understanding the Fourier transform of a function where the result in the frequency domain has imaginary components.
For example, if you take the Fourier transform of Sin[t] , the result is
What does this mean? I can't really graph it, so I am having trouble understanding it.
I can grasp a regular Fourier transform; it simply tells you what components are making up your signal wave. But when an imaginary I is thrown in there, what happens? How can the superposition of all those waves give you the real signal wave?
Does anybody have an intuition they could share?

Code:
I Sqrt[\[Pi]/2] DiracDelta[-1 + \[Omega]] -
I Sqrt[\[Pi]/2] DiracDelta[1 + \[Omega]]
