comment Derive forward Euler method for two-variable function
the function x(t0,x0) is a function of two variables, but it is expanded in only one of them.

comment Derive forward Euler method for two-variable function
Great answer. I knew of the geometrical interpretation, just needed assurance on the Taylor expansion.

comment Prove that there are no fixed points in a non-autonomous system
Maybe it's my understanding of fixed points that is somewhat lacking. Is it a necessary condition for a fixed point to occur that $\dot x_1 = 0, \dot x_2 = 0, ... \dot x_{n+1} = 0$?

comment Forced nonlinear oscillator - analytical methods
It was a great help, thanks. I've just verified the validity numerically - the solution trajectories of Duffing's equation converges to one attractor when there is one solution, and one of two attractors depending on initial conditions when there are three solutions (one is unstable). So it works!

Now THIS is math: "We will ignore these terms because...(e.g., γ is small, etc. etc.)." Physicist? ;-)
