# How to plot trajectories of the Rossler System [duplicate]

This is my current homework problem. I have completed parts a and b, but am now stuck on part c. I'm not sure what it means by plot the trajectories with different initial conditions, nor am I 100% sure how to do that. I know because of my positive eigenvalues that the solution will be unstable but after that I'm lost. Any advice would be really great.

You could try NDSolve then ParametricPlot3D

Manipulate[
Module[{a = 0.25, b = 0.5, ode1, ode2, ode3, x, y, z, t},
ode1 = x'[t] == -y[t] - z[t];
ode2 = y'[t] == x[t] + a y[t];
ode3 = z'[t] == b + z[t] (x[t] - c);
sol = NDSolve[{ode1, ode2, ode3, x[0] == x0, y[0] == y0,
z[0] == z0}, {x[t], y[t], z[t]}, {t, 0, maxTime}, MaxSteps -> Infinity];
ParametricPlot3D[{x[t], y[t], z[t]} /. sol, {t, 0, maxTime},
PlotRange -> {{-15, 15}, {-15, 15}, {-10, 30}},
AxesLabel -> {"x(t)", "y(t)", "z(t)"}, BaseStyle -> 12,
ImageSize -> 400, PerformanceGoal -> "Quality", Mesh -> None]
