How to Write the Ray (Half-line) Symbol (↞) in LaTeX

In LaTeX, you can write the ray (half-line) symbol (↞) using the \twoheadleftarrow command. This command is part of the amssymb package, so you need to include this package in LaTeX document.

The following examples show how to write the ray (half-line) symbol in LaTeX.

How to Write the Ray (Half-line) Symbol in Text

We can use the \twoheadleftarrow command to write the ray (half-line) symbol in LaTeX document for text.

Suppose we want to write the ray (half-line) symbol in the text.

We can use the following LaTeX code to do so:

\documentclass{article}
\usepackage{amssymb}
\begin{document}

This is an example of using the ray (half-line) symbol \( \twoheadleftarrow \) in a sentence.

\end{document}

Output: 👇️

This is an example of using the ray (half-line) symbol ↞ in a sentence.

In this example, we use the \twoheadleftarrow command to display the ray (half-line) symbol in the text.

How to Write the Ray (Half-line) Symbol in Mathematical Expressions

For mathematical expressions, We can use the \twoheadleftarrow command to ensure proper formatting.

Suppose we would like to write mathematical expressions that contain the ray (half-line) symbol.

We can use the following LaTeX code to do so:

\documentclass{article}
\usepackage{amssymb}
\begin{document}

An inline mathematical expression: \( \twoheadleftarrow \).

A displayed mathematical expression:
\[
\twoheadleftarrow
\]

\end{document}

Output: 👇️

In this example, we use the \twoheadleftarrow command to denote the ray (half-line) symbol in both inline and displayed mathematical expressions.

Conclusion

We can use the \twoheadleftarrow command from the amssymb package for both text and mathematical expressions. This ensures that the ray (half-line) symbol is properly formatted and displayed in LaTeX document.
