- Finding a Coordinate Matrix In Exercises 14, find the coordinate matrix x in Rn relative to the standard basis. x=(5,2)arrow_forwardTrue or false? det(A) is defined only for a square matrix A.arrow_forwardDetermine Symmetric and Orthogonal Matrices In Exercises 25-32, determine wheter the matrix is symmetric, orthogonal, both, or neither. A=[4503501035045]arrow_forward
- Proof Let A be an nn square matrix. Prove that the row vectors of A are linearly dependent if and only if the column vectors of A are linearly dependent.arrow_forwardDetermine Whether Two Matrices Are Similar In Exercises 21-24, determine whether the matrices are similar. If they are, find a matrix P such that A=P1BP. A=[100020002],B=[133353331]arrow_forwardFinding a Coordinate Matrix In Exercises 19-24, find the coordinate matrix of wrelative to the orthonormal basis Bin Rn. w=(1,2), B={(21313,31313),(31313,21313)}arrow_forward
