Fourier transform of a shifted sine wave
.
I figured it out, I made a mistake when I assumed that the time shift was ##(t-4)##, but the function can be rewritten as ##\sin(4t-4) =...

Thank you very much. I found the eigenvectors to be v1 = [1 , -Zc^-1] and v2 = [1 , Zc^-1]. My professor verified it, but he also said...
