The characteristic equation is an essential concept in the field of linear algebra, particularly when it comes to identifying the eigenvalues of a matrix. This equation is derived by equating the determinant of the matrix, less a certain variable (typically represented as λ), multiplied by the identity matrix, to zero. The solutions to this equation reveal the eigenvalues.
