Euclidean Normal Forms of Two-Dimensional Quadrics
|A B C D E F G H I J K L M N O P Q R S T U V W X Y Z||overview|
|intersecting pair of lines|
|parallel pair of lines|
The normal forms are uniquely determined up to permutation of subscripts and in the case of conical quadrics up to multiplication by a constant .
The values are set to be positive and are called lengths of the principal axes of the quadric.
|intersecting pair of lines||coincident lines|
|parallel pair of lines||parabola|
