- Determine Symmetric and Orthogonal Matrices In Exercises 25-32, determine wheter the matrix is symmetric, orthogonal, both, or neither. A=[4503501035045]arrow_forwardTrue or False? In Exercises 7376, 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 Addition of matrices is not commutative. b The transpose of the sum of matrices is equal to the sum of the transposes of the matrices.arrow_forwardOrthogonally Diagonalizable Matrices In Exercise 39-42, determine whether the matrix is orthogonally diagonalizable.
