 Author Comment/Response jf 02/04/13 10:59am Simplify does not have many tools to use. FullSimplify can do it, if you give it a hint what you mean by "simple". In[1]:= FullSimplify[Conjugate[E^(I x) x+E^(I y) y],{{x,y}\[Element]Reals}, ComplexityFunction->Depth] Out[1]= x Cos[x]+y Cos[y]-I x Sin[x]-I y Sin[y] ComplexExpand is the usual way to push through complex manipulations. In[2]:= ComplexExpand[Conjugate[E^(I x) x+E^(I y) y],{{x,y}\[Element]Reals}] Out[2]= x Cos[x]+y Cos[y]-I (x Sin[x]+y Sin[y]) TrigToExp will turn the outputs back to exponentials. In[3]:= TrigToExp[%] Out[3]= x E^(-I*x) + y E^(-I*y) URL: http://reference.wolfram.com/mathematica/ref/ComplexExpand.html,
