Many LaTeX users are confused about the correct source code for different symbols because of LaTeX’s enormous symbols capability. LaTeX also supports the Delta symbol. A Delta symbol indicates changes in a variable and is a Greek alphabet. Most Greek letters have their name as the syntax and are generally easy to use.
The Delta symbol in LaTeX looks complicated but is simple to use in reality. You only need to learn a simple source code to use different types of Delta symbols in LaTeX. This tutorial will explain how to write and use the Delta symbol in LaTeX effortlessly.
How to Use Delta Symbol in LaTeX
The Delta symbol is invariably used in Mathematical equations and formula. Hence, if you are a Math student, researcher, or professor, it is highly likely that you would use the delta symbol often.
Like many Greek alphabets, the source code for the delta symbol in LaTex is \Delta. We can use different types of Delta symbols, so let’s start with the uppercase Delta symbol:
Uppercase Delta Symbol
Let’s start writing the delta symbol on a standard text document, denoted using the document class, “article.” Now, please create the following source code:
\begin{document}
${\Delta}$
\end{document}
The output for the above code would be as follows:
If you want to use the vector Delta symbol, then simply put \vec with the ${\Delta}$:
\begin{document}
$\vec{\Delta}$
\end{document}
After executing the above source code, you will get the below output:
Lowercase Delta Symbol
You can use the lowercase delta symbol in LaTeX through the following source code:
\begin{document}
${\delta}$
\end{document}
Output:
By comparing uppercase and lowercase Delta symbols, you can see that the uppercase Delta symbol requires {\Delta} and the lowercase Delta symbol requires {\delta}.
Similarly, you can create a vector lowercase Delta symbol using \vec source code:
\begin{document}
$\vec{\delta}$
\end{document}
Output:
Wrapping Up
In this tutorial, we have provided the easiest ways to write and use the Delta symbol in LaTeX. Additionally, you can do several other modifications to the symbol using other LaTex packages, which are not limited.
After mastering the basic steps, you can choose different document classes and packages to test and see how the symbol appears in each combination.
