July 30, 2023

To write the long right double arrow symbol (⟹) in LaTeX, use the LaTeX command \Longrightarrow. It will add ⟹ arrow in the text.

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

Symbol Overview

Symbol: Long Right Double Arrow

Unicode: U+27F9

Type: Mathematical and Logical Symbol

Package Requirement: None (built-in symbol)

Argument: None (no additional arguments needed)

LaTeX Command: \Longrightarrow

Example: ⟹

Description

The long right double arrow is a built-in symbol represented as a two long arrows pointing to the right. In mathematics context, it is used to represents the rightward implication. It indicates the statement on the left-hand side logically implies to the statement on the right-hand side.

Syntax

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

\Longrightarrow

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

Using the Long Right Double Arrow Symbol in a Mathematical Expression

\documentclass{article}
\begin{document}
\[ x^2 > 25 \Longrightarrow x > 5 \]
\end{document}

Output: 👇️

x^2 > 25 ⟹ x > 5

Here in the above example, the inequality x^2 > 25 logically implies to x > 5

Using the Long Right Double Arrow Symbol in Logical Statement

\documentclass{article}
\begin{document}
\[ (p \land q) \Longrightarrow (q \land p) \]
\end{document}

Output: 👇️

(p ∧ q) ⟹ (q ∧ p)

In the above example, (p \land q) logically implies (q \land p).

Applications

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

Represents rightward implication between logical statements.
Indicates mathematical implications.

Conclusion

Using the long right double arrow symbol in LaTeX documents, you can use it in document to represent rightward implication between logical statements and mathematical expressions. It helps to create visually appealing and formatted documents with enhanced mathematical and logical representations.
