SUMMARY

The discussion centers on the properties of eigenvalues and their order in the context of the matrix [1, 1; 4, 1]. The eigenvalues identified are 3 and -1. It is established that the order of eigenvalues, whether λ1=3 and λ2=-1 or vice versa, does not affect the general solution of the system. The general solution can be expressed as c1*e^-t[1, -2] + c2*e^3t[1, 2], and the sequence of terms does not alter the validity of the solution.

PREREQUISITES

I have a general question regarding eigenvalues/vectors. Say you are working on a matrix
[ 1, 1; 4, 1] and you find the eigenvalues to be 3 and -1.
Does it matter which eigenvalue is first...meaning does it matter when it is λ1= 3 and λ2=-1 or the other way around?
When you write out the general solution in the form of c1*e^-t[1, -2] + c2*e^3t[1, 2] , how do you know which eigenvalue is written first? In other words why can the general solution not be written as c1*e^3t[1, 2] + c2*e^-t[1, -2]?

No. It doesn't matter at all.
 


Thank you
