- Finding a Value: Find x such that the matrix is equal to its own inverse. A=3x23arrow_forwardVerifying the Inverse of a Matrix Calculate the products AB and BA to verify that B is the inverse of A. A=[131140132]B=[834211101]arrow_forwardGuided Proof Prove that the inverse of a symmetric non-singular matrix is symmetric. Getting Started: To prove that the inverse of A is symmetric, you need to show that A-1T=A-1. i Let A be symmetric, nonsingular matrix. ii This means that AT=A and A-1 exists. iii Use the properties of the transpose to show that A-1T is equal to A-1.arrow_forward
