Hello Steve, I suggest not to use RealOnly. With the package loaded, there are horrible mistakes with 5.0. (Let us call it "bugs") For example : In[3]:= << "Miscellaneous`RealOnly`" In[10]:= Integrate[1/(x^2 + x + 1), x] Out[10]= x/(1 + x + x^2) Which is wrong, of course ! So it is better to use ComplexExpand and Simplify[expr,Element[x,Reals]] and so on!
