Ive verified that both forms agree for e^(-t)*sin(t) too.

Hello. Thanks for your reply. What you're doing is not calculating the Fourier Transform. It is easy to get the Fourier Transform from the Laplace Transform if we restrict our function to just one side of the plane (left-sided or right sided). If a function is left-sided or right-sided then to get the Fourier Transform, you evaluate the Laplace Transform and then substitute s=jw or s=-jw. This is what you seem to be doing. But what about the Fourier Transform of a dc signal which goes from -inf to +inf ? How do you calculate that ? Or how do calculate the FT of e^(j*2*t) ?
