WebApr 7, 2024 · A = ( a b c d) whose roots, as you know, are the eigenvalues of A: c A ( λ) = det ( λ I − A) = det ( λ − a − b − c λ − d) = ( λ − a) ( λ − d) − ( − b) ( − c) = λ 2 − ( a + d) λ + ( a d − b c) Now, c A is a quadratic function of λ, so it has no real roots---equivalently, A has no real eigenvalues---if its discriminant Δ is negative:

Sometimes, when we multiply a matrix by a vector, we get the same result as multiplying the vector by a scalar : A vector that satisfies this equation for some value of is called an eigenvector of , and the value of is called the corresponding eigenvalue. WebMay 20, 2014 · Every nonzero vector is an eigenvector of the identity matrix, with eigenvalue equal to 1. But it is possible to choose two orthogonal eigenvectors. Finally, as for explicitly calculating the eigenvalues in the 2x2 case, did you try simply calculating the determinant of and setting it equal to zero? markchampignoner
