find the eigenvalues for this first example, and then derive it properly in equation (3). Example 1. The matrix A has two eigenvalues D 1 and D 1=2. Look at det.A I /: .. 5 Ax3 D 3x3 : I notice again that eigenvectors are perpendicular when A is symmetric. The 3 by 3 matrix produced a third-degree (cubic) polynomial for det.A.
eigenvalue of A. 6. Definition: The eigenspace of the n ? n matrix A corresponding to the eigenvalue ? of A is the set of all eigenvectors of A corresponding to ?. 7. We're not used to analyzing equations like Ax = ?x where the unknown vector x appears on both sides of the equation. Let's find an equivalent equation in
We solve this using Gaussian elimination. We start by exchaning first and last row to get the zero in the bottom left corner (we could of course instead reduce to a lower triangular matrix rather than upper as we do here): -1 3 -1. 1 1 1. 0 1 0. x1 x2 x3.. = 0. Next we add row 1 to row 2:.. -1 3 -1. 0 4 0.
The only problem now is that you have to factor a cubic ?. Find one root, then use synthetic (or long) division to get the quadratic factor, then factor that (if possible) triangular or diagonal matrix. n n. ?. The eigenvalues are on the diagonal!

Now, to find the associated eigenvectors, we solve the equation (A ? ?jI)x = 0 for j = 1,2,3. Using the eigenvalue ?3 = 1, we have. (A ? I)x =.. 6x1 ? 3x3.
