WebIn real world applications, eigenvalues is a number that tells you how much variance there is in the data in a specific direction. The determinant of a matrix is also used in one of the inverse of a 3x3 matrix shortcuts. This shortcut involves taking the reciprocal of the determinant of a 3x3 matrix, and then multiplying by the adjugate matrix. WebApr 30, 2024 · I am being asked to find the eigenvalues for this matrix. It mentions that some tricks can be used instead of having to use $det(A-\lambda I)$. I understand how to do it that way, but what is a shortcut I can use for this matrix? Thanks. Solution is …
WebAug 19, 2016 · The eigenvalues of A are the roots of the characteristic polynomial p(t). Solving t4 − 1 = 0, we obtain the eigenvalues ± 1, ± i, where i = √− 1.
