How to use LaTeX Right Arrow Symbol

July 30, 2023

To write the right arrow symbol (→) in LaTeX, use the LaTeX command \rightarrow. It will add → arrow in the text.

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

Symbol Overview

Symbol: Right Arrow

Unicode: U+2192

Type: Mathematical

Package Requirement: None (built-in symbol)

Argument: None (no additional arguments needed)

LaTeX Command: \rightarrow

Example: →

Description

The right arrow is a built-in symbol available in LaTeX, is used to indicate a rightward direction. In mathematics context, it is used to represents the relationships such as mappings, functions, and transformations. In logical context, it is used in operations such as “implies” or “if-then”.

Syntax

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

\rightarrow

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

Using the Right Arrow Symbol in a Mathematical Expression

\documentclass{article}
\begin{document}
\[ f: X \rightarrow Y \]
\end{document}

Output: 👇️

f : X → Y

Here in the above example, f: X \rightarrow Y represents a mapping. Function f that maps elements from set X to Y.

Using the Right Arrow Symbol in Logical Statement

\documentclass{article}
\begin{document}
\[ P \land Q \rightarrow (P \lor \neg Q) \]
\end{document}

Output: 👇️

P ∧ Q → (P ∨ ¬Q)

In the above example, the \rightarrow represents the “implies” operation in the logical statement. Logical statement is true when the both ‘P’ and ‘Q’ are true, or ‘P’ is true and ‘Q’ is false.

Applications

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

Represents mappings, functions, and transformations in mathematical expression or equations.
Indicates logical relationship or implication in logical statement.

Conclusion

Using the right arrow symbol in LaTeX documents, you can use it in document where rightward direction, mapping, implication and conditional operations are required. It helps to create visually appealing and formatted documents with enhanced mathematical and logical representations.
