In Algebra, the sigma symbol (Σ) indicates the summation operator. The symbol, Σ, offers the simplest form of writing the sum of components in a series. In mathematics, the sigma symbol is used to indicate a sum. The simple (Σ) and double (ΣΣ) are two sigma symbols you can use in Algebra.
The simple sigma symbol is used to express a sum of multiple values, while the double sigma symbol is used as the double sum in a specific situation. Hence, it is essential to write the sigma symbol when you are writing a research paper or a document. This tutorial will demonstrate how to write and use sigma symbols in LaTeX.
How To Use a Sigma Symbol in LaTeX
Let’s start with an example to write the sigma symbol with the following source code:
\usepackage{amsmath}
\begin{document}
\[\sum_{n=1}^{5}2n\]
\end{document}
Output:
Similarly, you can write the double sigma symbol through the following source code:
\usepackage{amsmath}
\begin{document}
\[\sum_{a=2}^{4}\sum_{b=3}^{5}(a+b)=x\]
\end{document}
Output
Let’s take another example to create a force limit with the sigma symbol. The following is the source code to create a limit:
\usepackage{amsmath}
\begin{document}
$\sum_{x=1} ^{\infty} y_z a^z$
\end{document}
Output:
Conclusion
It is effortless to write and use a sigma symbol in LaTeX. We have included ways to use both simple and double sigma symbols. In Algebra, there are a few cases where you have to use the sigma symbol with a limit. That’s why we explained the complete writing method and using single or double sigma with a particular limit. We hope the information in this article helps you use the sigma symbol.
