Rectangular Hyperbola With Horizontal/vertical Asymptotes (Cartesian Coordinates)
Rectangular hyperbolas with the coordinate axes parallel to their asymptotes have the equation
- .
These are equilateral hyperbolas (eccentricity ) with semi-major axis and semi-minor axis given by .
The simplest example of rectangular hyperbolas occurs when the center (h, k) is at the origin:
describing quantities x and y that are inversely proportional. By rotating the coordinate axes counterclockwise by 45 degrees, with the new coordinate axes labelled the equation of the hyperbola is given by canonical form

Famous quotes containing the words horizontal and/or vertical:
“In bourgeois society, the French and the industrial revolution transformed the authorization of political space. The political revolution put an end to the formalized hierarchy of the ancien regimé.... Concurrently, the industrial revolution subverted the social hierarchy upon which the old political space was based. It transformed the experience of society from one of vertical hierarchy to one of horizontal class stratification.”
—Donald M. Lowe, U.S. historian, educator. History of Bourgeois Perception, ch. 4, University of Chicago Press (1982)
“I tell you, hopeless grief is passionless;
That only men incredulous of despair,
Half-taught in anguish, through the midnight air
Beat upward to God’s throne in loud access
Of shrieking and reproach. Full desertness,
In souls as countries, lieth silent-bare
Under the blanching, vertical eye-glare
Of the absolute Heavens.”
—Elizabeth Barrett Browning (1806–1861)
