How to Write Chi Symbol (χ) in LaTeX

In LaTeX, you can write the chi symbol using the \chi command for the lowercase chi (χ).

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

How to Write the Chi Symbol in Text

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

Example: Chi Symbol in Text

Suppose we want to write the chi 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 chi symbol \(\chi\) in a sentence.

\end{document}

Output: 👇️

This is an example of using the chi symbol χ in a sentence.

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

How to Write the Chi Symbol in Mathematical Expressions

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

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

We can use the following LaTeX code to do so:

\documentclass{article}
\begin{document}

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

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

\end{document}

Output: 👇️

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

Conclusion

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