I think you are confused because you're doing the math on paper with
real sin/cos functions. The complex signal sources produce complex
oscillations ($s_f(t)=e^{j2\pi f t}$), which do not have symmetrical
spectrum.
Do the math with the exponential function; it get's easier than what you
have to do
Can you plz explain Martin or give me a link atleast...thnx in advance

component(f1-f2) but only the addition component(f1+f2)...why is that??
That is actually the mathematically correct thing
