Finding eigenvalues using the characteristic equation - Titta på

The eigenvalues of the Jacobian are, in general, complex numbers. Let λj = µj +iνj, where µj and νj are, respectively, the real and imaginary parts of the eigenvalue. this system will have complex eigenvalues, we do not need this information to solve the system though. When presented with a linear system of any sort, we have methods for solving it regardless of the type of eigenvalues it has.1 With this in mind, our rst step in solving any linear system is to nd the eigenvalues of the coe cient matrix. Complex Eigenvalues OCW 18.03SC so that the real and imaginary parts of x give respectively the two real so­ lutions x 1 = eat(v 1 cos(bt) − v 2 sin(bt)) , x 2 = eat(v 1 sin(bt)+ v 2 cos(bt)) . (2) These solutions are linearly independent: they are two truly different solu­ tions. The general solution is given by their linear combinations c 1x 1 + c 2x 2. When you have the system of equations: x ′ = A x A = [ a 11 a 12 a 21 a 22] Show that when you have purely imaginary eigenvalues the trajectories in the phase plane x1 and x2 is an ellipse.
