Let's be brutally honest: Eigenvectors is usually taught terribly in textbooks. You don't need to be a genius to master this; you just need to understand one specific mental model.
Did you make this error?
- The Trap: forgetting the fundamental equation Ax = λx
- The Proof: Read this scenario: An eigenvector is a vector that, when multiplied by a matrix A, doesn't change direction—it only scales by the eigenvalue λ. It is the 'axis of rotation' for that transformation.
If your logic doesn't match the proof above, you've fallen for the trap. Erase it and start over.
