cartesian axis
31Y-axis — /ˈwaɪ æksəs / (say wuy aksuhs) noun the vertical reference axis in a two dimensional Cartesian coordinate system …
32Curvilinear coordinates — Curvilinear, affine, and Cartesian coordinates in two dimensional space Curvilinear coordinates are a coordinate system for Euclidean space in which the coordinate lines may be curved. These coordinates may be derived from a set of Cartesian… …
33Rotation matrix — In linear algebra, a rotation matrix is a matrix that is used to perform a rotation in Euclidean space. For example the matrix rotates points in the xy Cartesian plane counterclockwise through an angle θ about the origin of the Cartesian… …
34Versor — In mathematics, a versor is a directed great circle arc that corresponds to a quaternion of norm one. In geometry and physics, a versor is sometimes defined as a unit vector indicating the orientation of a directed axis (such as a Cartesian axis) …
35Orientation (vector space) — See also: orientation (geometry) The left handed orientation is shown on the left, and the right handed on the right. In mathematics, orientation is a notion that in two dimensions allows one to say when a cycle goes around clockwise or… …
36Axial multipole moments — are a series expansionof the electric potential of acharge distribution localized close to the origin along one Cartesian axis, denoted here as the z axis. However, the axial multipole expansion can also be applied to any potential or field that… …
37Magneto-optical trap — experimental setup of the MOT A magneto optical trap (abbreviated MOT) is a device that uses both laser cooling with magneto optical trapping in order to produce samples of cold, trapped, neutral atoms at temperatures as low as several… …
38automation — /aw teuh may sheuhn/, n. 1. the technique, method, or system of operating or controlling a process by highly automatic means, as by electronic devices, reducing human intervention to a minimum. 2. a mechanical device, operated electronically,… …
39Analytic geometry — Cartesian coordinates. Analytic geometry, or analytical geometry has two different meanings in mathematics. The modern and advanced meaning refers to the geometry of analytic varieties. This article focuses on the classical and elementary meaning …
