Defined `\dag`

and `\dagger`

commands for dagger symbols and `\textdagger`

commands for special text mode.

Symbol | Dagger |
---|---|

Type of symbol | Mathematics (Matrix) |

Package | No |

Argument | No |

Latex command | `\dag` |

Example | `\dag` → † |

```
\documentclass{article}
\begin{document}
$ \dag $\\ [6pt]
$ \dagger $\\[6pt]
% Dagger use in text mode
\textdagger
\end{document}
```

**Output : **

## Double dagger symbol

Use of double dagger symbol is much less. And different packages have the same command. But, there are morphological differences between the symbols.

```
\documentclass{article}
\begin{document}
$ \ddag $\\ [6pt]
$ \ddagger $\\[6pt]
% Double dagger use in text mode
\textdaggerdbl
\end{document}
```

**Output : **

## Use of dagger symbol as superscript

The dagger symbol is mathematically used as a hermitian adjoint. Below are various examples with the help of latex.

```
\documentclass{article}
\begin{document}
$$ \textit{A}^\dag = \textit{A} $$
$$ \langle P|\alpha\; as \; \alpha^\dag |P\rangle $$
$$ (\tilde{\textit{A}} \tilde{\textit{B}})^\dag = \tilde{\textit{B}}^\dag \tilde{\textit{A}}^\dag , $$
$$ (\tilde{\textit{A}} \tilde{\textit{B}} \cdots \tilde{\textit{Z}})^\dag = \tilde{\textit{Z}}^\dag \cdots \tilde{\textit{B}}^\dag \tilde{\textit{A}}^\dag . $$
\end{document}
```

**Output : **
