The symbol zeta is a letter of the Greek alphabet. This symbol is commonly used in mathematics and physics.
You don’t need any package to print this symbol in a LaTeX document, you just need to use LaTeX’s default \zeta
command.
Symbol/Unicode | Zeta/U+03B6 |
---|---|
Type of symbol | Greek small letter |
Package (requirement) | No |
Argument | No |
Latex command | \zeta |
Example | \zeta → ζ |
Below are some examples of how this symbol is used in LaTeX.
\documentclass{article}
\begin{document}
\[ \zeta(2)=\frac{\pi^2}{6} \]
\[ \zeta(s)=\sum^\infty_{n=1}\frac{1}{n^s} \]
\[ \frac{1}{\zeta(s)} \]
\end{document}
Output :
Zeta symbol using upgreek package
There is another way to print Zeta symbols on latex. For this, you need to use a package which is upgreek. This package provides a \upzeta
command that you can use to print this symbol to a LaTeX document.
But in this case, the output will be slightly different. let’s see
\documentclass{article}
\usepackage{upgreek}
\begin{document}
\[ \verb|\zeta|\rightarrow \zeta \quad \verb|\upzeta|\rightarrow \upzeta \]
\[ \upzeta(2)=\frac{\pi^2}{6} \]
\[ \upzeta(s)=\sum^\infty_{n=1}\frac{1}{n^s} \]
\[ \frac{1}{\upzeta(s)} \]
\end{document}
Output :
