rbrack

Represents a right square bracket character (]) in mathematical expressions and delimiters.

Overview

Serves as a closing delimiter in mathematical notation, particularly useful when standard keyboard brackets are insufficient or when specific sizing is needed.

  • Commonly paired with \lbrack to create matching bracket pairs
  • Often used in set notation, matrix definitions, and interval notation
  • Provides better spacing and scaling compared to standard keyboard brackets when used in mathematical contexts
  • Particularly valuable in displayed equations where proper mathematical typography is important

Examples

Using right bracket in a set builder notation

{x∈R∣x>0]\{x \in \mathbb{R} | x > 0 \rbrack 
\{x \in \mathbb{R} | x > 0 \rbrack

Half-open interval notation in real analysis

(a,b]={x∈R∣a<x≤b}(a, b\rbrack = \{x \in \mathbb{R} | a < x \leq b\} 
(a, b\rbrack = \{x \in \mathbb{R} | a < x \leq b\}
