Hi, Can someone help me on this one. I would like a list of coordinates so that I can analyze them further and possibly import into a "prettier" graphing package. What should I do when using the NDSolve function? I have tried the menu command: Input -> Get Graphics Coordinates. This requires me to use Mod1 key which I don't have on my keyboard. How can I get coordinates of the plot from the following: Pends[init1_, init2_, time_, k_, {c_, w_, p_}] := Module[{}, pend = NDSolve[{ x1''[t] + c x1'[t] + ((1 + p Cos[w t])) Sin[x1[t]] == k (x2[t] - x1[t]), x2''[t] + c x2'[t] + ((1 + p Cos[w t])) Sin[x2[t]] == k (x1[t] - x2[t]), x1[0] == init1[[1]], x1'[0] == init1[[2]], x2[0] == init2[[1]], x2'[0] == init2[[2]]}, {x1, x2}, {t, 0, time}, MaxSteps -> 200000]; xd[t_] := x1[t] /. pend[[1]]; xdd[t_] :=x1'[t] /.pend[[1]]; xr[t_] := x2[t] /. pend[[1]]; xrd[t_] :=x2'[t] /.pend[[1]]; ]; c = 0.1; w = 2.0; p = 2.0; Pends[{1.37, 0}, {-1.17, 0}, 5000, 0.0, {c, w, p}]; ParametricPlot[{ {xd[t], xdd[t]}, {xr[t], xrd[t]}}, {t, 1000, 1500}]; Winston
