How to Write the Set Intersection Symbol (∩) in LaTeX

In LaTeX, you can write the set intersection symbol (∩) using the \cap command.

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

How to Write the Set Intersection Symbol in Text

We can use the \cap command to write the set intersection symbol in LaTeX document for text.

Suppose we want to write the set intersection 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 set intersection symbol \(A \cap B\) in a sentence.

\end{document}

Output: 👇️

This is an example of using the set intersection symbol A ∩ B in a sentence.

In this example, we use the \cap command to display the set intersection symbol in the text.

How to Write the Set Intersection Symbol in Mathematical Expressions

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

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

We can use the following LaTeX code to do so:

\documentclass{article}
\usepackage{amsmath}
\begin{document}

An inline mathematical expression: \( A \cap B \).

A displayed mathematical expression:
\[
A \cap B = \{ x \mid x \in A \text{ and } x \in B \}
\]

\end{document}

Output: 👇️

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

Conclusion

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