Four-dimensional space ( 4D) is the mathematical extension of the concept of three-dimensional space (3D). Three-dimensional space is the simplest possible abstraction of the observation that one needs only three numbers, called dimensions, to describe the sizes or locations of objects in the everyday world.
India is a federal constitutional republic governed under a parliamentary system consisting of 28 states and 8 union territories. [ 1] All states, as well as the union territories of Jammu and Kashmir, Puducherry and the National Capital Territory of Delhi, have elected legislatures and governments, both patterned on the Westminster model.
A hierarchy of 4D point groups and some subgroups. Vertical positioning is grouped by order. Blue, green, and pink colors show reflectional, hybrid, and rotational groups. In geometry, a point group in four dimensions is an isometry group in four dimensions that leaves the origin fixed, or correspondingly, an isometry group of a 3-sphere .

Viète. de Moivre. Euler. Fourier. v. t. e. In trigonometry, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined. Geometrically, these are identities involving certain functions of one or more angles.
4D Server. 4D ( 4th Dimension, or Silver Surfer, as it was known during early development) is a relational database management system and integrated development environment developed by Laurent Ribardière. [ 3] 4D was created in 1984 [ 4] and had a slightly delayed public release for Macintosh in 1987 [ 5][ 6][ 7] with its own programming ...
A four-dimensional product (4D product) considers a physical product as a life-like entity capable of changing form and physical properties autonomously over time. It is an evolving field of product design practice and research linked to similar concepts at the material scale (programmable matter and four-dimensional printing), however, typically utilizes sensors and actuators in order to ...
