The following seems to work: In:= FullSimplify[Arg[E^((2 Pi n + x) I)], x > -Pi && x <= Pi && Element[n, Integers]] Out= x Does that help? --Anthony -----Original Message----- From: Neal Becker [mailto:ndbecker2 at gmail.com] Sent: Saturday, March 31, 2012 1:42 AM To: mathgroup at smc.vnet.net Subject: [mg125763] simplify Arg[E^(I x)]? Why doesn't this simplify? Fullsimplify[Arg[E^(I x)], x \[Element] Reals] I expect to get 'x'. Is there some way I can get this to simplify?
