Question
Find a 3 x 3 symmetric matrix M with eigenvalues A1 = 1 and A2 = 3 whose
geometric multiplicities are 2 and 1 respectively, such that:
1. (1, –1,1)*, (2, 0, 1)' are eigenvectors for 2.
2. (–1,1,2)' is an eigenvector for 3.
If we had replaced (-1, 1,2)' in item (2) by (–1, 1, 1)', would you have been
able to find such an M? If we had replaced the eigenvalue A by 5, would
you have been able to find such an M?
