How to Write Zeta Symbol (ζ) in LaTeX

In LaTeX, you can write the zeta symbol using the \zeta command for the lowercase zeta (ζ) and the \Zeta command for the uppercase zeta (Ζ).

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

How to Write the Zeta Symbol in Text

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

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

\end{document}

Output: 👇️

This is an example of using the zeta symbol ζ in a sentence.

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

How to Write the Zeta Symbol in Mathematical Expressions

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

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

We can use the following LaTeX code to do so:

\documentclass{article}
\begin{document}

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

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

\end{document}

Output: 👇️

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

Conclusion

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