Exercise 4.1.6: Sketch a phase portrait that shows an unstable limit cycle. The image I included below is meant to help with the exercise above. It is the background information given. This new kind of friction then gives us a new differential equation A simulation of this equation results in the trajectories shown in Figure 4.8, right. spring friction Figure 4.8: Upper: spring force and friction force for the Rayleigh clarinet model. Lower Left: Two representative trajectories for this model....
HELP Math 244 Fake Final Exam 2e syatem 13. 116 points Consider the non-linear system dt a) Use r -x2 + y2 to write dr as a function of r. b) This system has a limit cycle. Identify it, and determine whether it is stable or unstable. dr (t may help to draw the phese ine for the DE di )) e) The systemhas only one critical point, at the origin. (You do not need to prove this.) What, specifically,...
For the Hamiltonian syste m we did in class: 2. 3 Ic (1) Show that it's a Hamiltonian system with a Hamiltonian function (2) Show that for each c > 0, {(z,y) є R2 . H(z,y) c} is a bounded invariant set of the dynamical system (in fact, it's also closed) (3) Find all the equilibria of this system. Show that H-() is made up of one equilibium point and two homoclinic orbits attached to it. (4) Sketch the invariant...
