- 1—F
- 2The transformation T(A) = A^T from R5×5 to R5×5 is an isomorphismT
- 3—T
- 4If the n×n matrices A and B are orthogonal matrices, A+B must be orthogonal as well.F
- 5Consider an orthonormal basis~u1,~u2,···,~un in Rn. The least square solution of the system Ax=un where A= [u1,u2,···,un−1] is x=0.T
- 6< f,g >=f(1)g(1) +f(2)g(2) is an inner product in P1.T
- 7Let A be an n×n matrix. If λ is an eigenvalue of A, then λ^2+λ+1 is an eigenvalue of the matrix A^2+A+In.T
