Dear Sirs, I have some questions about how long a computer can calculate, without damages on hard wear. More specifically speaking, I intend to depict trajectories on (k, c) axis, which are derived from programming on Mathematica. My program is as follows: << Graphics`ImplicitPlot` L = 48; a = 0.1; A = 1; r = 0.1; t = 0.046296296296296294`; ImplicitPlot[A r L (1 - a)((1 -t) c k^a == (a+(1-a)(1- t)) L^2 (1-a)^2 (1- t )^3 k^(3a-1) +L(1-a) c (1- t) (-A(a+(1-a)(1- t))(2- t)-(1-a)(1- t)^2 +A a(1- t)) k^(2a-1) +A c^2 (A(a+(1-a)(1- t))+(1-a)(1- t) -A a(1- t)) k^(a-1) +A^2 r c^2, {k, 0.8, 1.5}] This program seems to work well. However, I cannot obtain the curve which should be derived from the above program, though my computer continues to calculate more than fifteen minutes. I would like to know how long a computer can calculate without damages on hardware, and additionally how long it takes to obtain the required curve based on my computer. Especially, my computer is PowerBook G4 with 1.5 GHz processor. Sincerely, Fujio Takata.
