How to Write Alpha Symbol (α) in LaTeX

In LaTeX, you can write the alpha symbol using the \alpha command for the lowercase alpha (α) and the \Alpha command for the uppercase alpha (Α).

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

How to Write the Alpha Symbol in Text

You can use the \alpha command to write the lowercase alpha symbol in LaTeX document for text.

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

\end{document}

Output: 👇️

This is an example of using the alpha symbol α in a sentence.

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

How to Write the Alpha Symbol in Mathematical Expressions

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

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

We can use the following LaTeX code to do so:

\documentclass{article}
\begin{document}

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

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

\end{document}

Output: 👇️

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

Conclusion

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