The axes of a two-dimensional Cartesian system divide the plane into four infinite regions, called quadrants, each bounded by two half-axes.
These are often numbered from 1st to 4th and denoted by Roman numerals: I (where the signs of the two coordinates are (+,+)), II (−,+), III (−,−), and IV (+,−). When the axes are drawn according to the mathematical custom, the numbering goes counter-clockwise starting from the upper right ("northeast") quadrant.
The Quadrant Cycle Company was a company in Birmingham, England that was established in 1890 as a bicycle manufacturer. They advanced to make motorcycles from 1899 until their demise in 1928. They also made a tricar called Carette in 1899 and a small number of cars for about two years around 1906.
The company exhibited a car chassis with a four-speed Lloyd gearbox of the style known as "crossed rollers"; this allowed direct drive at all speeds. The used 14/16 or 20/22 hp engines made by White and Poppe.

A Cartesian coordinate system is a coordinate system that specifies each point uniquely in a plane by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular directed lines, measured in the same unit of length. Each reference line is called a coordinate axis or just axis of the system, and the point where they meet is its origin, usually at ordered pair (0, 0). The coordinates can also be defined as the positions of the perpendicular projections of the point onto the two axes, expressed as signed distances from the origin.
One can use the same principle to specify the position of any point in three-dimensional space by three Cartesian coordinates, its signed distances to three mutually perpendicular planes (or, equivalently, by its perpendicular projection onto three mutually perpendicular lines). In general, n Cartesian coordinates (an element of real n-space) specify the point in an n-dimensional Euclidean space for any dimension n. These coordinates are equal, up to sign, to distances from the point to n mutually perpendicular hyperplanes.
A disciple is a follower and student of a mentor, teacher, or other figure. It can refer to:
Śrāvaka (Sanskrit) or Sāvaka (Pali) means "hearer" or, more generally, "disciple". This term is used in Buddhism and Jainism. In Jainism, a śrāvaka is any lay Jain so the term śrāvaka has been used for the Jain community itself (for example see Sarak and Sarawagi).
In Buddhism, the term is sometimes reserved for distinguished disciples of the Buddha.
In early Buddhism, a śrāvaka or śrāvikā is a disciple who accepts:
Disciple (Swedish: Lärjungen) is a 2013 Finnish drama film directed by Ulrika Bengts. The film was selected as the Finnish entry for the Best Foreign Language Film at the 86th Academy Awards, but it was not nominated.
