Hi... I want get Abs[z] and Arg[z] and I'm using the AbsArg[] command but, it works for 'numeric' complex... For generic expression, I've trouble. Can someone help me?
Thanks... :-D
It takes some nudging:
FullSimplify[ComplexExpand[AbsArg[1/(I w - 2)^2], TargetFunctions -> {Re, Im}], Element[w, Reals]]
Arg is not easy to deal with symbolically, because of the discontinuities.
