How to Write Kappa Symbol (κ) in LaTeX

In LaTeX, you can write the kappa symbol using the \kappa command for the lowercase kappa (κ) and the \Kappa command for the uppercase kappa (Κ).

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

How to Write the Kappa Symbol in Text

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

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

\end{document}

Output: 👇️

This is an example of using the kappa symbol κ in a sentence.

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

How to Write the Kappa Symbol in Mathematical Expressions

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

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

We can use the following LaTeX code to do so:

\documentclass{article}
\begin{document}

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

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

\end{document}

Output: 👇️

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

Conclusion

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