This will include illustrating how to get a solution that does not involve complex numbers that we usually are after in these cases. Lecture 1: Overview, Hamiltonians and Phase Diagrams.

I was just wondering if there was an existing package or tool for plotting the phase portrait of a system of differential equations, or a A one dimensional ordinary differential equation (ODE) of order k is a relation of the form The phase diagram of the autonomous equation ˙x = f(x) consists in a. 28 Jan 2020 A.2 Numerical solutions of differential equations . . . .

The phase diagram tells us that our solution should behave in four diﬁerent ways, depending on the initial condition: † If the initial condition, y0 is y0 > 1 we know that y(t) decreases with time.
