Then every solution can be written as. x → = x → c + x → p. where x → c is a solution to the associated homogeneous equation ( x → = P x →). So the procedure will be the same as for single equations.

Geometrical interpretation of complex eigenvectors in a system of ...

WebIn the case that M has real values, it is easy to give a geometric interpretation of the eigenvectors in the (x, y) plane: they are the directions along which the dynamical system is "sucked" or "expelled" from the stable point. If the eigenvalues are complex, then the eigenvectors are complex too. WebAlso, systems of linear differential equations very naturally lead to linear transformations where the eigenvectors and eigenvalues play a key role in helping you solve the system, because they "de-couple" the system, by allowing you to think of a complex system in which each of the variables affects the derivative of the others as a system in ...
