Symbol/Unicode | Big Pi/U+03A0 |
---|---|
Type of symbol | Greek capital letter |
Package (requirement) | No |
Argument | No |
Latex command | \Pi |
Example | \Pi → Π |
You need to use the \Pi
command to print the Big Pi symbol in a latex document. This is the default command of latex.
\documentclass{article}
\begin{document}
\[ Big\; pi =\Pi \]
\end{document}
Output :
Big pi with limits
You need to use \Pi_{subscript}^{superscript}
command to write Limits with the Big Pie symbol. But I will not recommend this process when you use limits.
\documentclass{article}
\begin{document}
\[ \Pi_{i=1}^\infty a_i \]
\[ \Pi_{i=1}^5 i^2 \]
\end{document}
Output :
As you can see in the example above, the symbol does not look very good with limits, so it is best to use the \prod
command and use \prod_{subscript}^{superscript}
to add limits. This is also a default latex command. Below are some examples.
\documentclass{article}
\begin{document}
\[ \prod_{i=1}^\infty a_i \]
\[ \prod_{i=1}^5 i^2 \]
\[ \prod_{i=1}^k \frac{n+1-i}{i} \]
\end{document}
Output :
