WebJun 8, 2016 · To illustrate the point I've added phase plane portraits below showing examples of both equilibrium types. These plots have come from solving two simple linear ODE systems. Each system of ODEs has an equilibrium at $(x,y)=(0,0)$ and as you can see the solution trajectories on the LHS plot spiral into their equilibrium point.

WebThe path travelled by the point in a solution is called a trajectory of the system. A picture of the trajectories is called a phase portrait of the system. In the animated version of this page, you can see the moving points as well as the trajectories. But on paper, the best we can do is to use arrows to indicate the direction of motion. Web1. Determine the type of the system, i.e., sink (node), source, saddle, center, spiral source, spiral sink, center. 2. Draw the phase portrait of the system. If the eigenvalue are real you need to compute the eigenvectors and indicate them clearly on the phase portrait. 3. Draw a rough graph of a typical solution y 1(t), y 2(t). Note that you ...
