Hi, you can't because Mathematica knows nothing about data types. You can Simplify[]/FullSimplify[] with Element[x,Reals] and you can look what Needs["Miscellaneous`RealOnly`"] can do for you. And you can say x /: Im[x]=0 x /: Re[x]=x Regards Jens Aniruddha Chakraborty wrote: > > Dear all, > can any one tell me how can I define "x" , real variable? > > thanks > > aniruddha
