How to Write Change in X (Δx) in LaTeX

In LaTeX, you can write the change in x (Δx) using the \Delta command for the uppercase delta (Δ) and the variable x.

The following examples show how to write Δx in LaTeX.

How to Write Δx in Text

We can use the \Delta command to write Δx in LaTeX document for text.

Suppose we want to write Δx in the text.

We can use the following LaTeX code to do so:

\documentclass{article}
\begin{document}

This is an example of using the change in x symbol \(\Delta x\) in a sentence.

\end{document}

Output: 👇️

This is an example of using the change in x symbol Δx in a sentence.

In this example, we use the \Delta command to display the uppercase delta symbol followed by the variable x in the text.

How to Write Δx 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 Δx.

We can use the following LaTeX code to do so:

\documentclass{article}
\begin{document}

An inline mathematical expression: \( \Delta x \).

A displayed mathematical expression:
\[
\Delta x = x_2 - x_1
\]

\end{document}

Output: 👇️

Δx

In this example, we use the \Delta command to denote the change in x (Δx) in both inline and displayed mathematical expressions.

Conclusion

We can use the \Delta command followed by the variable x for both text and mathematical expressions.

This ensures that the change in x symbol is properly formatted and displayed in LaTeX document.
