The four quadrants of a Cartesian coordinate system. The axes of a two-dimensional Cartesian system divide the plane into four infinite regions, called quadrants, each bounded by two half-axes. The axes themselves are, in general, not part of the respective quadrants.

A Cartesian coordinate system in two dimensions (also called a rectangular coordinate system or an orthogonal coordinate system [8]) is defined by an ordered pair of perpendicular lines (axes), a single unit of length for both axes, and an orientation for each axis. The point where the axes meet is taken as the origin for both, thus turning ...
I create a 4-Quadrant coordinate system and just modified the template to reflect this version. I think it is much better than the current 1-Quadrant coordinate system. The new one divids the Go board into four parts (North-East, North-West, South-East, and South-West), not simply one.
Gaspard Monge's four quadrants and two planes. Modern orthographic projection is derived from Gaspard Monge's descriptive geometry. [4] Monge defined a reference system of two viewing planes, horizontal H ("ground") and vertical V ("backdrop"). These two planes intersect to partition 3D space into 4 quadrants, which he labeled: I: above H, in ...
Illustration of a Cartesian coordinate plane. Four points are marked and labeled with their coordinates: (2,3) in green, (−3,1) in red, (−1.5,−2.5) in blue, and the origin (0,0) in purple. In analytic geometry, the plane is given a coordinate system, by which every point has a pair of real number coordinates.
Let (x, y, z) be the standard Cartesian coordinates, and (ρ, θ, φ) the spherical coordinates, with θ the angle measured away from the +Z axis (as , see conventions in spherical coordinates). As φ has a range of 360° the same considerations as in polar (2 dimensional) coordinates apply whenever an arctangent of it is taken. θ has a range ...
A quad chart is a form of technical documentation used to briefly describe an invention or other innovation through writing, illustration and/or photographs. [1] Such documents are described as "quad" charts because they are divided into four quadrants laid out on a landscape perspective.
