July 30, 2023

To write the left harpoon up arrow symbol (↼) in LaTeX, use the LaTeX command \leftharpoonup. It will add ↼ arrow in the text.

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

Symbol Overview

Symbol: Left Harpoon-Up Arrow

Unicode: U+21BC

Type: Mathematical and Vector Symbol

Package Requirement: None (built-in symbol)

Argument: None (no additional arguments needed)

LaTeX Command: \leftharpoonup

Example: ↼

Description

The left harpoon up arrow is a built-in symbol available in LaTeX represented as an arrow pointing to the left and upwards. It is widely used in mathematics and vectors. In mathematics context, it is used to represent a vector or transformation that point to the left and upwards.

It is used in vector calculus to dentore vector fields.

Syntax

The LaTeX command \leftharpoonup is used to display the left harpoon up arrow symbol.

\leftharpoonup

Let’s understand using left harpoon-up arrow symbol in various domains like mathematics, vectors context with the help of examples.

Using the Left Harpoon Up Arrow Symbol in a Mathematical Expression

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

Output: 👇️

⃗v↼

Here in the above example, \vec{v} represents a vector, and \leftharpoonup indicates the left and upwards direction of the vector.

Using the Left harpoon-up Arrow Symbol in Vector Calculus

\documentclass{article}
\begin{document}
\[ \nabla \times \mathbf{F} = 0 \leftharpoonup \]
\end{document}

Output: 👇️

∇ × F = 0 ↼

In the above example, the \nabla \times \mathbf{F} represents the curl of the vector field \mathbf{F}, and \leftharpoonup represents that the curl is zero in the left and upward direction.

Applications

The left harpoon-up arrow symbol has versatile applications in LaTeX documents such as:

Represents vectors or transformations that point to the left and upwards direction in mathematical expression or equations.
Indicates vector fields or directions in vector calculus.

Conclusion

Using the left harpoon up arrow symbol in LaTeX documents, you can use it in document where leftward and upward direction, vector and vector fields pointing to the left and upwards are required. It helps to create visually appealing and formatted documents with enhanced mathematical and logical representations.
