If A is an invertible symmetric matrix the `A^-1` is
A. a diagonal matrix
B. symmetric
C. skew symmetric
D. none of these

Inverse of diagonal matrix is (A) a diagonal matrix (B) symmetric (C) skew symmetric (D) none of these

if B is skew symmetric matrix then find matrix ABA^(T) is symmetric or skew symmetric

The inverse of an invertible symmetric matrix is a symmetric matrix.

Symmetric & Skew metric matrix

The inverse of a diagonal matrix is a. a diagonal matrix b. a skew symmetric matrix c. a symmetric matrix d. none of these

If the matrix A is both symmetric and skew-symmetric , then

If B is a symmetric matrix,write whether the matrix ABA^(T) is symmetric or skew- symmetric.

If A is skew-symmetric matrix then A^(2) is a symmetric matrix.

If A is a non-singular symmetric matrix, write whether A^(-1) is symmetric or skew-symmetric.

If A is skew-symmetric matrix, then trace of A is
