Hello, I was wondering why this works IN[]:= Refine[Re[x + y I], Element[x , Reals] && Element[y , Reals]] Out[]:= x But this does not In[]:= Refine[Re[1/(x + y I)], Element[x , Reals] && Element[y , Reals]] Out[]:= Re[1/(x + y I)] Is there a nice built in way to get the real and imaginary parts of a complex function?
