Hello everybody ! Hans, Bill and others... > I am struggling with dealing with Expressions. For most sake and purposes I > can find a fix and solve my small problems, but I never feel very assured.
I have the same problem when I try to expand cos(2*x) in cos(x)^2-sin(x)^2. The expand(cos(x+y)) is right, but expand (cos(2*x)) remains cos(2*x). Martin and Bill help me, but I can't see the pretty way to write my own expand which also compute for cos(2*x). A possible method is here : http://wiki.axiom-developer.org/SandBoxDistributedExpression Have a good day ! François, I'm always waiting for a pretty expand (cos(3*x)) ! _______________________________________________ Axiom-developer mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/axiom-developer
