x' = 3(y - x)which exhibit chaotic behavior.
y' = -xz + 26.5x - y
z' = xy - z
The graph shows (x(t), y(t)), the projection of the trajectory into the x,y plane. The color is a function of time.
If you use Java capable browser, such as Netscape 2.0, an animated version of the Lorenz attractor will appear here.
