Let A be a non-zero matrix that is diagonalizable. Show that A" # 0, for any positive integer r. Definition: A nilpotent matrix is a square matrix M such that M = 0 for some positive integer k. nilpotent matrices are not diagoanalizable. 0 1 Show that 0 0 1 is not diagonalizable. 0 00 Show that a non-zero n x n upper triangular matrix with zero diagonal entries is not diagonalizable.
