Web12 nov. 2024 · Since adding a multiple of the identity to a matrix just shifts eigenvalues, the eigenvalues of A + tI are the quantities t − rk. Hence, since the determinant of a matrix is the product of its eigenvalues, we have det (A + tI) = (t − r1)(t − r2)…(t − rn) = p(t) as required.

WebDeterminants and matrices, in linear algebra, are used to solve linear equations by applying Cramer’s rule to a set of non-homogeneous equations which are in linear form. Determinants are calculated for square matrices only. If the determinant of a matrix is zero, it is called a singular determinant and if it is one, then it is known as unimodular. 1. ^ Lang 1985, §VII.1 2. ^ Wildberger, Norman J. (2010).
