Definition and examples of open interval define open …

An open interval does not include its endpoints, and is indicated with parentheses. For example, (0, 1) means greater than 0 and less than 1. This means (0, 1) = {x 0 < x < 1}. This interval can also be denoted by ]0, 1[, see below. A closed interval is an interval which includes all its limit points, and is denoted with square brackets. For example, [0, 1] means greater than or equal to 0 and less than or equal to 1. Web25 de jun. de 2014 · The expressions "A includes x" and "A contains x" are also used to mean set membership, however some authors use them to mean instead "x is a subset of A". Another possible notation for the same relation is {\displaystyle A\ni x,} A\ni x, meaning "A contains x", though it is used less often.
