Real Number Set Diagram

The Real Number Set is a fundamental concept in mathematics that is used to represent all possible values of a continuous one-dimensional quantity such as distance, duration, or temperature . It is denoted by the symbol R and is defined as the set of all rational and irrational numbers .

A real number can be almost uniquely represented by an infinite decimal expansion . The real numbers are fundamental in calculus and more generally in all mathematics, in particular by their role in the classical definitions of limits, continuity, and derivatives . The set of real numbers is sometimes called “the reals” .

The real numbers include the rational numbers, such as the integer -5 and the fraction 4/3. The rest of the real numbers are called irrational numbers. Some irrational numbers (as well as all the rationals) are the root of a polynomial with integer coefficients, such as the square root of 2 = 1.414…; these are called algebraic numbers. There are also real numbers which are not, such as ? = 3.1415…; these are called transcendental numbers .

Real numbers can be thought of as all points on a line called the number line or real line, where the points corresponding to integers (…, -2, -1, 0, 1, 2, …) are equally spaced. Conversely, analytic geometry is the association of points on lines (especially axis lines) to real numbers such that geometric displacements are proportional to differences between corresponding numbers .

Real numbers are completely characterized by their fundamental properties that can be summarized by saying that they form an ordered field that is Dedekind complete . This implies that one can manipulate real numbers and compute with them, without knowing how they can be defined . Real numbers are used in many areas of mathematics, including algebra, geometry, calculus, and analysis .

In summary, the Real Number Set is a set of all possible values of a continuous one-dimensional quantity. It includes
