How to use LaTeX Double Right Arrow Symbol

July 30, 2023

To write the double 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 rigtwards double arrow (⇒) in the LaTeX document and their significance in the mathematical expressions and logical statements.

Symbol Overview

Symbol: Double Right Arrow

Unicode: U+21D2

Type: Mathematical

Package Requirement: None (built-in symbol)

Argument: None (no additional arguments needed)

LaTeX Command: \Rightarrow

Example: ⇒

Description

The double right arrow represented as a double-headed right pointing arrow (⇒) is available in LaTeX. It is used to indicate a rightward directional relationship. In mathematics context, it is used to represents the logical implication or “if-then” statements. In logical context, it is used in operations such as “if and only if”.

Syntax

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

\Rightarrow

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

Using the Double Right Arrow Symbol in a Mathematical Expression

\documentclass{article}
\begin{document}
\[ x \Rightarrow y \]
\end{document}

Output: 👇️

x ⇒ y

Here in the above example, x \Rightarrow y represents a logical implication, indicating that if ‘x’ is true then ‘y’ is also true.

Using the Double-headed 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 “if and only if” operation in the logical statement. Logical statement is true when the both ‘P’ and ‘Q’ have the same truth value.

Applications

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

Represents logical implications or “if-then” statements in mathematical expression or equations.
Indicates logical relationship or “if and only if” in logical statement.

Conclusion

Using the double sided right arrow symbol in LaTeX documents, you can use it in document where rightward directional relationships, logical implications, and logical equivalence are required. It helps to create visually appealing and formatted documents with enhanced mathematical and logical representations.
