A Free damped vibration of a system of 2 dof, demostration

[Jhair]

Hi,I need help please, i want to know how to solve de differential equation of a system of two degree of freedom using Heigenvalues or Heigenvectors or if I can use any another way to solve this kind of equations.

I may need a bit more information to help you with your problem. First, by two degrees of freedom are you referring to a system of two coupled oscillators? Or are you referring to a simple mass on a spring problem in two dimensions?
