Prove that the inverse of a symmetric nonsingular matrix is symmetric. Getting Started: To prove that the inverse of A is symmetric, you need to show that (A^-1)^T=A^-1. (i) Let A be a symmetric, nonsingular matrix. (ii) This means that A^T=A and A^-1 exists. (iii) Use the properties of the transpose to show that (A^-1)^T is equal to A^-1 | Numerade
