I did some experiments for you f=3*x assigns a symbolic expression in x to the variable f. In this case, you should use named argument like f(x=2) On the other hand, f(x)=3*x assigns to f a symbolic function in x. Then you may just type f(2) Cheers Kwankyu --~--~-~--~~-

OK, I see, if I define f(x) then I can use f(2) to evaluate. Otherwise, if I define only f, then f(x=2) or f.subs(2) is required. Thanx, A. Jorge Garcia http://calcpage.tripod.com Teacher & Professor Applied Mathematics, Physics & Computer Science Baldwin Senior High School & Nassau Community
