8.1.24 – Find the eigenvalues and eigenvectors of the given matrix. Remark upon any case where an eigenbasis of real eigenvectors does not exist.
Solution
Using the rule , where A is the matrix given above, it is easy to find our eigenvalues.
Thus, there is only one eigenvalue for this matrix, .
Now we will find the eigenvectors associated with the above eigenvalue, using the rule
.
Thus, the corresponding eigenvectors are of the form .
You could also say that the eigenvectors .
