i'm dealing with simple trig funcions, Sin[], Cos[] and so on ... 'm also using Conjugate and my expressions are full of Cos[a]* Now if a is real there's no risk to have Complex number. I have may variables, and I would like to avoid a redefinition of $Assuming where I have to list every varaible I use. I prefer, if exists, somethig like: "Dear Mathematica 5.1, every variable I use is Real, wathever its name is ... If I'll need complex number I'll use :ii: to enter the imaginary unit. See you at next calculation. Regards Your faithfull User." Is it possible?
