Trace and determinant of characteristic polynomial.

WebIgor Konovalov. 10 years ago. To find the eigenvalues you have to find a characteristic polynomial P which you then have to set equal to zero. So in this case P is equal to (λ-5) (λ+1). Set this to zero and solve for λ. So you get λ-5=0 which gives λ=5 and λ+1=0 which gives λ= -1. 1 comment. WebMay 20, 2016 · the characteristic polynomial can be found using the formula: CP = -λ 3 + tr(A)λ 2 - 1/2( tr(A) 2 - tr(A 2)) λ + det(A), where: tr(A) is the trace of 3x3 matrix; det(A) is the determinant of 3x3 matrix; Characteristic Polynomial for a 2x2 Matrix.
