Texts: 3. Let u and v be two non-zero column vectors in R^n, and let A = uv^T. (a) Show that every vector w which is orthogonal to v is an eigenvector of A belonging to the eigenvalue 0. (b) Conclude that X = 0 is an eigenvalue with geometric multiplicity n - 1. (c) Show that the n-th eigenvalue is Tr(A) = u^T * v (Recall that Tr(A) is the sum of all the diagonal entries of A). (d) Conclude that if u^T * v ≠0, then A is diagonalizable.
