How to use LaTeX Hooked Right Arrow Symbol

To write the hooked right arrow symbol (↪) in LaTeX, use the LaTeX command \hookrightarrow. It will add ↪ arrow in the text.

In this article, we will discuss how to use hooked right arrow (↪) in the LaTeX document and their significance in the mathematical expressions and logical statements.

Symbol Overview

Symbol: Hooked right Arrow

Unicode: U+21AA

Type: Mathematical and Vector Symbol

Package Requirement: None (built-in symbol)

Argument: None (no additional arguments needed)

LaTeX Command: \hookrightarrow

Example: ↪

Description

The hooked right arrow is a built-in symbol available in LaTeX represented as an arrow pointing to the right (↪). It is widely used in mathematics and vectors. In mathematics context, it is used to represents a rightward transformation.

Syntax

The LaTeX command \hookrightarrow is used to display the hooked right arrow symbol.

\hookrightarrow

Let’s understand using hooked right arrow symbol in various domains like mathematics, vectors context with the help of examples.

Using the Hooked Right Arrow Symbol in a Mathematical Expression

\documentclass{article}
\begin{document}
\[ x^2 + 1 \hookrightarrow x^2 \]
\end{document}

Output: 👇️

x2 + 1 ↪ x2

Here in the above example, x^2 + 1 represents the result, and x^2 is transformed rightward with the hooked right arrow.

Using the Hooked Right Arrow Symbol in Vector Representations

\documentclass{article}
\begin{document}
\[ \vec{v} \hookrightarrow \vec{u} \]
\end{document}

Output: 👇️

⃗v ↪ ⃗u

In the above example, the \vec{v} and \vec{u} are vectors, and \hookrightarrowrepresents a rightward transformation from vector \vec{v} to vector \vec{u}.

Applications

The hooked right arrow symbol has versatile applications in LaTeX documents such as:

• Represents rightward transformations or steps in mathematical expressions.
• Indicates vector transformations or relations in vector spaces.

Conclusion

Using the hooked right arrow symbol in LaTeX documents, you can use it in document to represent rightward transformation and vector relations. It helps to create visually appealing and formatted documents with enhanced mathematical and logical representations.
