Question
True or false: If $\mathbf{w}_1, \ldots, \mathbf{w}_j$ is a Jordan chain for a matrix $A$, so are the scalar multiples $c \mathbf{w}_1, \ldots, c \mathbf{w}_j$ for all $c \neq 0$.
Step 1
A sequence of vectors $\mathbf{w}_1, \ldots, \mathbf{w}_j$ is called a Jordan chain for a matrix $A$ associated with an eigenvalue $\lambda$ if: - $\mathbf{w}_1$ is an eigenvector of $A$ corresponding to $\lambda$, i.e., $A \mathbf{w}_1 = \lambda \mathbf{w}_1$. - Show more…

True or false: if A is an n x n matrix with det(A) ≠ 0, then A is invertible and det(A)A^{-1} is equal to the transpose of the cofactor matrix of A.
True or false? (a) The determinant of $S^{-1} A S$ equals the determinant of $A$. (b) If det $A=0$ then at least one of the cofactors must be zero. (c) A matrix whose entries are 0 s and 1 s has determinant 1,0 , or $-1$.
