Homework Help Overview

The discussion revolves around the topic of degenerate eigenvalues and eigenvectors in the context of linear algebra, specifically focusing on matrices H and B. The original poster seeks clarification on why the matrices do not uniquely specify their eigenvectors despite having calculated them.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster has calculated eigenvalues and vectors for matrices H and B and questions the uniqueness of the eigenvectors due to degeneracy. Other participants express difficulty in finding three common eigenvectors and seek further understanding of the underlying reasons.

Homework Equations





The Attempt at a Solution



Ok so I've done A and have worked out eigenvalues and vectors of H and B

For H I get 4 possible eigenvectors (1,0,0) (0,1,1) (0,0,1) and (0,1,0) . The q is why does neither matrix uniquely specify its eigenvectors? I guess the answer is because the eigenvalues are degenrate (repeated)..but is there a clearer explanation as to why?

Thanks

Also - i can't seem to find three common eigen vectors.. I can only find (1,0,0) and (0.1.1)
 


anyoneeee?
 


why can't i find three common eigenvectors?
