How to Write Delta Symbol (δ) in LaTeX

In LaTeX, you can write the delta symbol using the \delta command for the lowercase delta (δ) and the \Delta command for the uppercase delta (Δ).

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

How to Write the Delta Symbol in Text

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

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

\end{document}

Output: 👇️

This is an example of using the delta symbol δ in a sentence.

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

How to Write the Delta Symbol in Mathematical Expressions

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

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

We can use the following LaTeX code to do so:

\documentclass{article}
\begin{document}

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

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

\end{document}

Output: 👇️

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

Conclusion

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