How to Write the Proportional To Symbol (∝) in LaTeX

In LaTeX, you can write the proportional to symbol (∝) using the \propto command.

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

How to Write the Proportional To Symbol in Text

We can use the \propto command to write the proportional to symbol in LaTeX document for text.

Suppose we want to write the proportional to 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 proportional to symbol \( a \propto b \) in a sentence.

\end{document}

Output: 👇️

This is an example of using the proportional to symbol a ∝ b in a sentence.

In this example, we use the \propto command to display the proportional to symbol in the text.

How to Write the Proportional To Symbol in Mathematical Expressions

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

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

We can use the following LaTeX code to do so:

\documentclass{article}
\begin{document}

An inline mathematical expression: \( a \propto b \).

A displayed mathematical expression:
\[
a \propto b
\]

\end{document}

Output: 👇️

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

Conclusion

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