One eigenvector is X = ( 1 i). It satisfies X T X = 0. However, replacing X T in your argument by X H (complex conjugate of transpose) will give you the correct conclusion that | λ | 2 = 1. Share Cite FollowShow that the eigenvalues of a real orthogonal matrix have unit modulus and that if \( \lambda \) is an eigenvalue then so is \( \lambda^{*} \). Hence argue that the eigenvalues of a \( 3 \times 3 \) real orthogonal matrix \( R \) must be a selection from \[ +1,-1 \text { and } \mathrm{e}^{\pm i \alpha} \text {. } \] Verify that det \( R=\pm 1 \). algebra 2 test 1
