A 2 i eigenvalues
Suppose A2=In and v≠0 is an eigenvector of A with eigenvalue λ then we have: Av=λv⟹A2v=Aλv⟹Inv=λ(Av)⟹v=λ2v⟹v(λ2−1)=0.,2014年4月24日 — The question is: Prove that if λ is an eigenvalue of a matrix A with corresponding eigenvector x, then λ2 is an eigenvalue of A2 with ...,Let. P(λ)=det(λI−A)=(λ−λ1)⋯(λ−λn). be the characteristic polynomial for A Then.,Suppose 0≠v∈V is an eigenvector of Awith eigenvalue λ , then. λv=Av=A2v=A(λv)=λAv=λ2v. So. (λ2−λ)v=0⟹λ2=λ⟺λ=0,1. A is a zero of x2−x , which means ...,The eigenvalues remain the same. Indeed, if λ is an eigenvalue for A with eigenvector v, then we have A2v=A(Av)=λAv=λ2v. So v is an eigenvector of A2 with ...,If v is an eigenvector of A with eigenvalue λ, then v=Iv=A2v=A(Av)=A(λv)=λ(Av)=λ2v. Thus, if λ is an eigenvalue of A and A2=I then λ2=1.,In either case we find that the first eigenvector is any 2 element column vector in which the two elements have equal magnitude and opposite sign. where k1 is ...,(λIn − A)v = 0.
