- ‘Of course, points on the real axis don't change because the complex conjugate of a real number is itself.’
- ‘Using a bit more trigonometry, we can determine the angle between two subsequent samples by multiplying one by the complex conjugate of the other and then taking the arc tangent of the product.’
- ‘The nice property of a complex conjugate pair is that their product is always a non-negative real number.’
- ‘In a publication in 1932 he gave a lower bound for the regulator of the units of an algebraic number field which depends only on the number of real conjugates and the number of pairs of complex conjugates.’
