How to use LaTeX Long Left Arrow Symbol

To write the long left arrow symbol (⟵) in LaTeX, use the LaTeX command \longleftarrow. It will add ⟵ arrow in the text.

In this article, we will discuss how to use long left arrow (⟵) in the LaTeX document and their significance in the mathematical expressions and vectors.

Symbol Overview

Symbol: Long Left Arrow

Unicode: U+27F5

Type: Mathematical and Vector Symbol

Package Requirement: None (built-in symbol)

Argument: None (no additional arguments needed)

LaTeX Command: \longleftarrow

Example: ⟵

Description

The long left arrow is a built-in symbol represented as a long arrow pointing to the left (⟵). It is widely used in mathematicas and vectors. In mathematics context, it is used to represents the directional relation or transformation that point to the left.

Syntax

The LaTeX command \longleftarrow is used to display the long left arrow symbol.

\longleftarrow

Let’s understand using LaTeX long left arrow symbol in various domains like mathematics, vectors with the help of examples.

Using the Long Left Arrow Symbol in a Mathematical Expression

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

Output: 👇️

x^2 ⟵ x^2 + 1

Here in the above example, the x^2 points to the left and becomes x^2 + 1.

Using the Left Arrow Symbol in Vector Representations

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

Output: 👇️

⃗u ⟵ ⃗v

In the above example, the \vec{u} and \vec{v} are vectors, and \longleftarrow denotes a transformation from vector \vec{v} to vector \vec{u} pointing to the left.

Applications

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

• Represents directional relations or transformations.
• Indicates vector representations or directions in vector spaces.

Conclusion

Using the long left arrow symbol in LaTeX documents, you can use it in document to represent relations and vectors transformation pointing to the left. It helps to create visually appealing and formatted documents with enhanced mathematical and logical representations.
