I'm a little confused on ODEsEx02. When doing plot_lorenz, we have 10 initial conditions for x(t) and z(t) right? So we should have 20 lines total on the graph, right?

Initial conditions come in pairs (x,z) and I interpreted that as ten separate graphs so you can get a sense of the behaviour of the lorenz

Then each of your 10 graphs have 2 lines, right?

No, because it is a parametric plot, x vs z of t, the curves should look pretty familiar

Wait, so it's not supposed to look like a ball of yarn from the underworld? Shoot. Thank you!

So for the Damped pendulum section in ODE3, it says the plot limits should be:
theta in [-2pi,2pi] and theta in [-10,10], so which one is supposed to be omega? (Cuz I'm guessing one of those is a misprint).
