Hello, Try ComplexExpand. Start reading ?ComplexExpand at the terminal. But be careful. For instance, if f:=a+I b then In[]:= Sqrt[f*Conjugate[f]//ComplexExpand] Out[]= Sqtr[a^2+b^2] but In[]:= Sqrt[f*Conjugate[f]]//ComplexExpand Out[]= Sqrt[(a+I b) Conjugate[a+I b]] Sincerely, Jesus ROJO -- --------------------------------------- | Jesus ROJO | | Dpto. de Matematica Aplicada | | E.T.S. de Ingenieros Industriales | | Paseo del Cauce s/n | | 47011 VALLADOLID, Spain | | Phone : 34 - 83 - 42 33 90 | | Fax : 34 - 83 - 42 34 06 | | e-mail: jesroj at wmatem.eis.uva.es | ---------------------------------------
