For most work, Maple doesn't require you to define symbolic variables. One does need to define local variables for a procedure, though. But that isn't the same thing. The having to define variables kind of put me off using Sage to start. It wasn't particularly clear in the documentation. My main problems now stem from missing symbolic manipulation commands some of which are being addressed by pynac. So, I'm kind of holding off until Sage 3.2 before really diving back in. >> > Well, that would be an improvement.
