Interval (mathematics) The addition x + a on the number line. All numbers greater than x and less than x + a fall within that open interval. In mathematics, a (real) interval is the set of all real numbers lying between two fixed endpoints with no "gaps". Each endpoint is either a real number or positive or negative infinity, indicating the ...
Interval arithmetic (also known as interval mathematics; interval analysis or interval computation) is a mathematical technique used to mitigate rounding and measurement errors in mathematical computation by computing function bounds. Numerical methods involving interval arithmetic can guarantee relatively reliable and mathematically correct ...
This represents the value (or values) of the argument x in the interval (−∞,−1] that minimizes (or minimize) the objective function x 2 + 1 (the actual minimum value of that function is not what the problem asks for). In this case, the answer is x = −1, since x = 0 is infeasible, that is, it does not belong to the feasible set. Similarly,

The common usage, much older than the general definition of functions between sets, is to not use double parentheses and to simply write f(x 1, x 2, …, x n). It is also common to abbreviate the n-tuple (x 1, x 2, …, x n) by using a notation similar to that for vectors, like boldface x, underline x, or overarrow x →. This article will use ...
A numeral system is a writing system for expressing numbers; that is, a mathematical notation for representing numbers of a given set, using digits or other symbols in a consistent manner. The same sequence of symbols may represent different numbers in different numeral systems. For example, "11" represents the number eleven in the decimal or ...
An interval graph is an undirected graph G formed from a family of intervals. by creating one vertex vi for each interval Si, and connecting two vertices vi and vj by an edge whenever the corresponding two sets have a nonempty intersection. That is, the edge set of G is. It is the intersection graph of the intervals.
Calculator input methods. There are various ways in which calculators interpret keystrokes. These can be categorized into two main types: On a single-step or immediate-execution calculator, the user presses a key for each operation, calculating all the intermediate results, before the final value is shown. [ 1 ][ 2 ][ 3 ] On an expression or ...
