How to Write Iota Symbol (ι) in LaTeX

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

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

How to Write the Iota Symbol in Text

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

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

\end{document}

Output: 👇️

This is an example of using the iota symbol ι in a sentence.

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

How to Write the Iota Symbol in Mathematical Expressions

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

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

We can use the following LaTeX code to do so:

\documentclass{article}
\begin{document}

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

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

\end{document}

Output: 👇️

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

Conclusion

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