Hi, if cosine and sine waves are exactly the same wave except cosine starts earlier in time, why do they have different Fourier Transforms? I know the cos would have an impulse at f=Fc with amplitude of 1, and sin would have an impulse at f=Fc and amplitude of 1/j. I don't understand why the amplitude of the sine goes complex in the amplitude spectrum just from having a different phase.
Hope you guys can explain it to me :)
