How to Write Xi Symbol (ξ) in LaTeX

In LaTeX, you can write the xi symbol using the \xi command for the lowercase xi (ξ) and the \Xi command for the uppercase xi (Ξ).

The following examples show how to write the xi symbol in LaTeX.

How to Write the Xi Symbol in Text

We can use the \xi command to write the lowercase xi symbol in LaTeX document for text.

Suppose we want to write the xi symbol in the text.

We can use the following LaTeX code to do so:

\documentclass{article}
\begin{document}

This is an example of using the xi symbol \(\xi\) in a sentence.

\end{document}

Output: 👇️

This is an example of using the xi symbol ξ in a sentence.

In this example, we use the \xi command to display the lowercase xi symbol in the text.

How to Write the Xi Symbol in Mathematical Expressions

For mathematical expressions, we can use the \xi command to ensure proper formatting.

Suppose we would like to write mathematical expressions that contain the xi symbol.

We can use the following LaTeX code to do so:

\documentclass{article}
\begin{document}

An inline mathematical expression: \( \alpha + \beta = \xi \).

A displayed mathematical expression:
\[
\alpha^2 + \beta^2 = \xi^2
\]

\end{document}

Output: 👇️

In this example, we ues the \xi command to denote the xi symbol in both inline and displayed mathematical expressions.

Conclusion

We can use the \xi command for both text and mathematical expressions. This ensures that the xi symbol is properly formatted and displayed in LaTeX document.
