‒‒‒‒TATIAHN ? ? ? ? ? Are the following statements true or false for a square matrix A? 1. A matrix A is singular if and only if 0 is an eigenvalue of A. 2. An n x n matrix A is diagonalizable if A has n linearly independent eigenvectors. 3. Finding an eigenvector of A might be difficult, but checking whether a given vector is in fact an eigenvector is easy. 4. If A is invertible, then A is diagonalizable. 5. The sum of two eigenvectors of a matrix is always an eigenvector.
