How to Write Mu Symbol (μ) in LaTeX

In LaTeX, you can write the mu symbol using the \mu command for the lowercase mu (μ) and the \Mu command for the uppercase mu (Μ).

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

How to Write the Mu Symbol in Text

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

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

\end{document}

Output: 👇️

This is an example of using the mu symbol μ in a sentence.

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

How to Write the Mu Symbol in Mathematical Expressions

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

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

We can use the following LaTeX code to do so:

\documentclass{article}
\begin{document}

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

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

\end{document}

Output: 👇️

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

Conclusion

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