Question:medium

Let \(A\) be a square matrix. Which of the following statement about eigenvectors is correct?

Show Hint

If \[ \boxed{ A\mathbf{x}=\lambda\mathbf{x}, } \] then every non-zero scalar multiple \[ \boxed{ k\mathbf{x},\;k\neq0, } \] is also an eigenvector corresponding to the same eigenvalue.

  • Eigen vectors are always unique
  • Eigen vectors are unique only if the eigen value has multiplicity \(1\)
  • Eigen vectors are unique up to a scalar multiple
  • Eigen vectors cannot be scaled
