How to Write Tau Symbol (τ) in LaTeX

In LaTeX, you can write the tau symbol using the \tau command for the lowercase tau (τ) and the \Tau command for the uppercase tau (Τ).

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

How to Write the Tau Symbol in Text

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

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

\end{document}

Output: 👇️

This is an example of using the tau symbol τ in a sentence.

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

How to Write the Tau Symbol in Mathematical Expressions

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

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

We can use the following LaTeX code to do so:

\documentclass{article}
\begin{document}

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

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

\end{document}

Output: 👇️

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

Conclusion

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