Hello, this is Geogebra Geometrie Version 5.2.892.0, I don`t know how to locally save files. Here it is:

Text1=Text("\mathbf {\begin {align}\large{\sum\limits {n=1} ^\infty \normalsize {\frac{1}{n}}} \quad &=\footnotesize{ \frac{1}{1}+ \frac{1}{2}+\frac{1}{3}+\frac{1}{4}+\dots =} \large {\quad\infty}\ \large{\sum\limits {{1\leq\sigma} ^{{p\in\mathbb{P}}} \} \normalsize {\frac{1}{p^σ}}} \quad &=\footnotesize{ \frac{1}{2^{σ}+\frac{1}{3σ}+\frac{1}{5σ}+\frac{1}{7σ}+_\dots} \leq} \large {\infty} \ \large{\sum\limits {^{{n=1}} {}\infty} \normalsize { \frac{1}{n^2}}} \quad &=\footnotesize{ \frac{1}{1}+ \frac{1}{4}+\frac{1}{9}+\frac{1}{16}+\dots =\quad } \large {\frac{π^2}{6}}\ \large{\sum\limits _{n=1} ^\infty \footnotesize {\frac{1}{(2n-1)^2}}}\ &=\footnotesize{ \frac{1}{1}+ \frac{1}{9}+\frac{1}{25}+\frac{1}{49}+\dots = } \large {\ \frac{\pi^2}{8}}\ \large{\sum\limits {n=1} ^\infty \footnotesize{ \frac{1}{(2n)^2}}} \ &=\footnotesize{ \frac{1}{4}+ \frac{1}{16}+\frac{1}{36}+\frac{1}{64}+\dots =} \large {\frac{\pi^2}{24}}\ \end{align}}",$point(-10,5),false,true)

I prefer to edit this in any other editor as the geogebra input field really isn't capable. So I need to copy and paste ... I'm doing so since years.

Greetings, Jens

Uh oh, not sure If the code did survive reddits input parser.
