Hi, I was working on some differntial equations and decided to have Mathematica plot some Phase-Space solutions, which was simply a plot of a circle of the form X^2+Y^2=R^2 - this resulted in several messages from Mathematica about saying that it was not a "Machine-Size Real Number" at several points on my range...I had a similar error message when I tried plotting Y^2=X (Plot[{Sqrt[X], - Sqrt[X]}, {X, -10, 10}])...I was still able to get a plot of my solution, but I was just wondering what caused these messages to appear and what they mean (I'm new to using Mathematica)...If anybody knows, please e-mail me. Thanks in advance. Mackie at dartmouth.edu -------------------- "Professor Dyson, what do you think about the many-worlds theory?" -Me "I don't like it." -Freeman Dyson
