Here are a couple of threads where similar issues were discussed: http://groups.google.com/group/comp.soft-sys.math.mathematica/browse_thread/thread/5d90a2a2f697f7c8/ http://groups.google.com/group/comp.soft-sys.math.mathematica/browse_thread/thread/a977993b567866d4/ Regards, Leonid On Mon, Dec 28, 2009 at 12:55 PM, Fabian <fabian.uriarte at gmail.com> wrote: > Dear Group- > > Why can't Mathematica evaluate "Re[]" here ? > > {Rm, Xm} \[Element] Reals; > Z = (Rm*\[ImaginaryJ] Xm)/(Rm + \[ImaginaryJ]*Xm); > Z = ComplexExpand[Z] > Re[Z] > > -Thank you > >
