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. WebNov 16, 2024 · In an asymptotically stable node or spiral all the trajectories will move in towards the equilibrium point as t increases, whereas a center (which is always stable) …

Web1. Determine the type of the system, i.e., sink, source, saddle, center, spiral source, spiral sink, center, degenerate eigenvalues. 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. If the eigenvalues are complex Webimproper nodal sink. The example shows the phase portrait and direction field of the system x0= 5 2 2 10 x with eigenvalues/vectors l1 = 9 l2 = 6 v1 = 1 2 ... this gives you a spiral source or sink, or a center. To determine the direction of rotation, choose a point (say (1,0)) and compute the direction vector at that point. ... cd ラベル印刷
