OPEN INTERVAL Meaning and
Definition
-
An open interval, in mathematics, refers to a subset of the real numbers that consists of all numbers between two specified values, excluding those values themselves. An open interval is denoted by parentheses. For example, if a and b are real numbers, and a < b, then the open interval between a and b is represented by (a, b). This means that any number x such that a < x < b belongs to the open interval (a, b). However, neither a nor b themselves are included in the interval.
The concept of an open interval can be extended to other number systems, such as the set of complex numbers. In this case, an open interval is defined as the set of all complex numbers z such that a < Re(z) < b and a < Im(z) < b, where Re(z) and Im(z) represent the real and imaginary parts of z, respectively.
Open intervals are often used in calculus, analysis, and number theory. They are particularly useful for defining the convergence of limits, continuity of functions, and other important mathematical concepts. The exclusion of the endpoints in an open interval distinguishes it from other types of intervals, such as closed intervals (which include the endpoints) and half-open intervals (which include one endpoint but not the other).

Etymology of OPEN INTERVAL
The term "open interval" is a mathematical concept used to describe a set of real numbers between two endpoints, where the endpoints themselves are not included. The etymology of the word "open" in this context comes from the Latin word "apertus", meaning "open" or "accessible". The term "interval" derives from the Latin word "intervallum", which refers to the space between two objects or points. So, the combination of these words gives rise to the term "open interval" to describe a range of numbers that is open-ended, not including the endpoints.
