Chapter 9, Problem 24(choose chapter or problem)
In this problem we show how small changes in the coefficients of a system of linear equations can affect a critical point that is a center. Consider the system x _ = _ 0 1 1 0 _ x. Show that the eigenvalues are i so that (0, 0) is a center. Now consider the system x _ = _ 1 1 _ x, where || is arbitrarily small. Show that the eigenvalues are i. Thus no matter how small || _= 0 is, the center becomes a spiral point. If < 0, the spiral point is asymptotically stable; if > 0, the spiral point is unstable. 2

ANSWER:Step 1 of 2
The linear equation of the system is as follows.
Find the eigenvalues.
Therefore, the eigenvalues are complex, so it can be said that the system has center and the system is stable.
Therefore, it is shown that the eigenvalues are so that is a center.
