This does not declare the symbols to be real, but it solves the given example, since ComplexExpand[] assumes all variables in the expression to be real: In[1]:= ComplexExpand[Conjugate[x+I y]] Out[1]= x-\[ImaginaryI] y Torsten wwolfe18 at comcast.net wrote: > This has been annoying me for a while. > Is there a way to declare symbols to be real so that > Re[x + i y] gives x and Conjugate[x + i y] gives x - i y etc? > > Warren Wolfe > > >
