Determinant and characteristic polynomial

WebThe characteristic equation of A is a polynomial equation, and to get polynomial coefficients you need to expand the determinant of matrix. For a 2x2 case we have a simple formula:, where trA is the trace of A (sum of its diagonal elements) and detA is the determinant of A. That is, WebThe Properties of Determinants Theorem, part 1, shows how to determine when a matrix of the form A Iis not invertible. The scalar equation det(A I) = 0 is called the characteristic …
