- Proof Prove that if A and B are similar matrices and A is nonsingular, then B is also nonsingular and A1 and B1 are similar matrices.arrow_forwardProof Prove that if A and B are similar matrices, then |A|=|B|. Is the converse true?arrow_forwardProof Prove that if A and B are nn skew-symmetric matrices, then A+B is skew-symmetric.arrow_forward
- Proof Let A be a nonsingular matrix. Prove that if B is row-equivalent to A, then B is also nonsingular.arrow_forwardProof Prove that if A is an nn matrix, then A-AT is skew-symmetric.arrow_forwardCAPSTONE Explain how to determine whether an nn matrix A is diagonalizable using a similar matrices, b eigenvectors, and c distinct eigenvalues.arrow_forward
- Finding the nullspace of a matrix in exercise 27-40, find the nullspace of the matrix. A=[2163]arrow_forwardFinding the Nullspace of a MatrixIn Exercises 27-40, find the nullspace of the matrix. A=[523121]arrow_forwardTrue or False? In Exercises 37 and 38, determine whether each statement is true or false. If a statement is true, give a reason or cite an appropriate statement from the text. If a statement is false, provide an example that shows the statement is not true in all cases or cite an appropriate statement from the text. a If A and B are similar nn matrix, then they have always the same characteristics polynomial equation. b The fact that an nn matrix A has n distinct eigenvalues does not guarantee that A is diagonalizable.arrow_forward
- Proof Prove that if matrix A is diagonalizable, then AT is diagonalizable.arrow_forwardFinding a Sequence of Elementary Matrix In Exercises 3336, find a sequence of elementary matrices whose product is the given nonsingular matrix. [2301]arrow_forwardProof Prove that each statement is true when A and B are square matrices of order n and c is a scalar. a TrA+B=TrA+TrB b TrcA=cTrAarrow_forward
