"WebSuppose vectors v and cv have eigenvalues p and q. So Av=pv, A (cv)=q (cv) A (cv)=c (Av). Substitute from the first equation to get A (cv)=c (pv) So from the second equation, q (cv)=c (pv) (qc)v= (cp)v Since v is an eigenvector, it cannot be the 0 vector, so qc=cp, or q=p. The eigenvalues are the same. 1 comment ( 2 votes) Upvote Flag Arsalan127 " - Graphing eigenvectors
