Dear MathGroup, _____________________________________ Question: Do anyone knows if using the palletes (Alebraic Manipulation, BasicMathInput, BasicTypesetting) in Mathematica 6 needs more stack memory that writing algebra in full form? ______________________________________ Problem: I am interested in check an equality: Side 1= Side 2 of the form: 24*n*y*y=-4*b+2*v*z-v*v/k*e^z With y,b,v,z,k,n variables which all but n are veeeeeery long expressions of the form: y:= b:= etc... and to make them look shorter I defined other expressions, so that y, b, v, etc, need other expressions to be complete. I know that the equality is analitically true, but I get using TrueQ(side 1, side2), PossibleZeroQ, that the equality is False. __________________________________________ Options: So, I think that the problem could be in: - Lack of memory, because Mathematica stops evaluating the notebook after the 16th definition, although I asked Mathematica about the memory used: MemoryInUse= 6,314,760 bites just before it stopped evaluating the notebook but I think Mathematica=B4s limit is about 19,654,528 bites. -Maybe I do not have enough computer memory, but I have 1GBite of RAM=1,073,741,824 bites. -Maybe I did not write well the definitions. ___________________________________________ Any comments or suggestions will be very appreciated, :) thank you very much in advance, Alejandra Lozada
