I am trying to expand rational polinomials, functions of I omega. All other variables are real ( I use ReIm.m to declare them real). ComplexExpand does not expand the Abs, like: In[1]:= <<Algebra`ReIm` In[2]:= w/: Im[w]=0 (* Declares w real *) Out[2]= 0 In[3]:= ComplexExpand[Abs[1+ 2 I w]] Out[3]= Abs[1 + 2 I w] Is there any way to expand it??
