Question

Объясните,что называют координатной осью.

Answer 1

Координатной осью называется прямая, на которой отмечена точка О (начало отсчета или начало координат), выбран масштаб, т.е. указан отрезок единичной длины для измерения расстояний (единичный или масштабный отрезок), и задано положительное направление.

Answer 2

What is a coordinate axis?

A coordinate axis is a line used to establish a reference system for locating points in a two-dimensional or three-dimensional space. It is an essential component of the Cartesian coordinate system, which was developed by René Descartes in the 17th century. The coordinate axis consists of two or three mutually perpendicular lines, known as the x-axis, y-axis, and z-axis in three-dimensional space. These axes intersect at a common point called the origin.

The x-axis represents the horizontal dimension, the y-axis represents the vertical dimension, and the z-axis represents the depth or height dimension in three-dimensional space. Each axis is labeled with numerical values that indicate the position of a point relative to the origin. The positive direction of the x-axis is to the right, the positive direction of the y-axis is upward, and the positive direction of the z-axis is outward from the origin.

The coordinate axis system allows us to describe the position of any point in space using a set of coordinates, typically represented as (x, y, z) in three-dimensional space. The x-coordinate represents the distance along the x-axis, the y-coordinate represents the distance along the y-axis, and the z-coordinate represents the distance along the z-axis.
