Problem 1
1.1 If A is an n x n matrix, prove that if A has n linearly independent eigenvalues, then AT is diagonalizable.
1.2 Diagonalize the matrix below with eigenvalues equal to -1 and 5.
0 | 1 | 1 |
2 | 1 | 2 |
3 | 3 |
2 |
1.3 Assume that A is 4 x 4 and has three different eigenvalues, if one of the eigenspaces is dimension 1 while the other is dimension 2, can A be undiagonalizable? Explain.
Answer for all 3 questions required.
