The focal form of the quadric in n dimensions
Published online by Cambridge University Press: 24 October 2008
Extract
The object of this note is to show that the equation of the quadric in n dimensions can be transformed to a ‘focus-directrix’ form which is exactly similar to those for two and three dimensions: this form is extended throughout by the introduction of a constant k. A short discussion of confocal quadrics is appended.
