If you are interested in using Mathematica for parallel computing on a dedicated cluster, or in a distributed grid environment, please let Paul Fish at Wolfram Research know. Seattle University's Mathematica license can be used for grid computing. Many departmental labs have Mathematica installed as well. That should suppress the error, assuming you are comfortable with the fact that sometimes Mathematica will make this maneuver to solve equations that are input as if they are numerical, but are better solved symbolically.Mathematica is currently installed in the following locations: Computer LabsĪll general or public-access labs. In the end, if ratnz is an issue, start your code with: Off The second solution is valid when tc<0 and tc <= c <= -2 tc (or when c=tc=0, which is the degenerate solution that includes both cases). (tc = 0) only when c=0 which should be obvious. Even correcting these minor issues: f1 = ta - tb + c į2 = ta*tc + ta*tb + 0.5*ta^2 + tb*tc + 0.5*tb^2 However, that's not really part of the issue. Second, these functions do not require delayed evaluation, so the := is superfluous. Better, generally, to use lowercase letters for n, c, d, etc. I believe there are a few ways to improve this, at least one of which has already been mentioned.įirst, capital C is a built-in symbol. There is a similar distinction between 0.5 and 1/2.
"0." represents the floating point real number that's just about as close to zero as Mathematica can figure. Yes, 0.-1.5C means -3C/2, but written in the language of "Real" rather than "Rational." Your input uses decimals, which Mathematica interprets as approximate/numerical data, not exact rationals.
