Maybe it is a very stupid question but I am having trouble with summing complex numbers in Mathematica. I have
q = l1 E^(2 π I t1) + l2 E^(2 π I t2)
t2 are known real numbers. I obtain an answer which is a set of four complex numbers.
I think it sums all the components one by one (Minkowski sum?), and I want just to sum two complex numbers to obtain a third one. What function should I use?
