Figure 6: Sensitive dependence on initial conditions: the two orbits of (a) -coordinates for initial points are (0.62, 0.52) and (0.63, 0.52); (b) -coordinates for initial points are (0.62, 0.52) and (0.62, 0.53); (c) -coordinates for initial points are (0.6, 0.5) and (0.61, 0.5); (d) -coordinates for initial points are (0.6, 0.5) and (0.6, 0.51).
