WebApr 3, 2024 · You could find the eigenvalues and eigenvectors algebraically, i.e. calculate the eigenvalues as the roots of the characteristic polynomial and solve a linear, homogeneous system per eigenvalue to find the corresponding eigenvector(s). Here however, they want you to use the geometrical interpretation of the reflection to find them … Web10 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.
