Recursion Limit & Symbolic Differentiation
Hi, I'm new to Mathemtica and I'm trying to differentiate a multi-variable function f(x,y,z). When doing so I get a recusion limit 256 reached message. When examining my equations, I don't see recursion in the expressions. It should be simple substitution of one expression into the other. (Its just easier for me to write it that way). How do I know if this is a valid message, and how do I know if my expressions will actually be solved / simplified by Mathematica if I increase the recursion limit? I have 2GB RAM and Mathematica fills it, then the Kernel runs out of memory and stops trying to solve the problem. Thanks.
