Symbols:Brackets/Angle Brackets

Symbol

Angle brackets are symbols used in a number of specific contexts.

They comprise the left angle bracket $\langle$ and the right angle bracket $\rangle$.

The $\LaTeX$ code for \(\langle\) is \langle .

The $\LaTeX$ code for \(\rangle\) is \rangle .

Usage

Angle brackets are used in the following contexts:

The specification of a point in polar coordinates: $\polar {r, \theta}$

To denote a sequence: $\sequence {s_n}$

To denote the set of images under an indexed family: $\family {x_i}_{i \mathop \in I}$

To denote a generator of a group or other algebraic structure: $\gen {a, b}$

This article is complete as far as it goes, but it could do with expansion. In particular: Plenty more usages, if only I could think of them You can help $\mathsf{Pr} \infty \mathsf{fWiki}$ by adding this information.
