I am trying to get some results expressed in the form Abs[x] Exp[I
theta].
So, if I type in
ComplexExpand[z,{z},TargetFunctions->{Abs,Arg}]//TrigToExp I get
Abs[z] Exp[I Arg[z]] which is what I want,
but if I type in ComplexExpand[x+ I y, TargetFunctions->{Abs,
Arg}]//TrigToExp I just get back x + I y.
Would someone explain this to me. I was expecting the output
Sqrt[x^2+y^2] Exp[I ArcTan[x,y]]
Since my results are in the form x + I y, the Mathematica output
doesnt do me any good.
thanks. jerry blimbaum
