Simplifying the factors of a complex number's imaginary part

[QUOTE="mfb, post: 5487381, member: 405866"] There is no formula that would make it easier. You can write all numbers as ##A=A_R+iA_I## and so on and then make a long list of summands that contribute to the imaginary part, e. g. ##A_RB_RC_RD_I + A_RB_RC_ID_R + \dots## (in total 8 components) but that is not very useful. If you know the numbers, where is the problem with just multiplying them? Complex conjugation just changes the sign of the imaginary part, apart from that nothing happens so it is easy to take into account. In your attached screenshot, two summands with c[sub]2[/sub] got lost. [/QUOTE]
