|
| 12. | The only possible measurement is between any two orthogonal states ( an orthonormal basis ).
|
| 13. | The sines and cosines in the Fourier series are an example of an orthonormal basis.
|
| 14. | The columns of the matrix form another orthonormal basis of " V ".
|
| 15. | Each orthonormal basis is a Parseval frame, but the converse is not always true.
|
| 16. | An orthonormal basis for Minkowski space necessarily consists of one timelike and three spacelike unit vectors.
|
| 17. | The resulting ordered orthonormal basis is precisely the "'TNB "'frame.
|
| 18. | Every countable orthonormal basis is equivalent to the standard unit vector basis in ! 2.
|
| 19. | Let be an orthonormal basis of.
|
| 20. | We say that is an " orthonormal basis " for if it is a basis and
