B. symmetric matrix
WebSo the vectorized way to describe a quadratic form like this is to take a matrix, a two by two matrix since this is two dimensions where a and c are in the diagonal and then b is on the other diagonal and we always think of these as being symmetric matrices so if you imagine kind of reflecting the whole matrix about this line, you'll get the same … WebSymmetric matrices play the same role as the real numbers do among the complex numbers. Their eigenvalues often have physical or geometrical interpretations. One can …

Did you know?
WebA, we can use this fact to find which eigenvalues of a symmetric matrix are greater or less than any real number b. This tells us a lot about the eigenvalues of A even if we can’t compute them directly. Positive definite matrices A positive definite matrix is a symmetric matrix A for which all eigenvalues are positive.
WebIn general, for any square skew-symmetric integral matrix B, we denote by A(B) the associated coefficient-free cluster algebra, as in [4]. We say that A(B) has rank n if B is … WebLet A and B be and two 3 × 3 matrices. If A is symmetric and B is skewsymmetric, then the matrix AB – BA is symmetric. Explanation: Let A be symmetric matrix and B be skew-symmetric matrix. ∴ A T = A and B T = –B Consider (AB – BA) T = (AB) T – (BA) T = B T A T – A T B T = (–B) (A) – (A) (–B) = –BA + AB = AB – BA
