The sum formulas for 1/π

[edit]

I see that you are also searching for sum series for 1/π that are constructed by using modular elliptic functions. Please click on these links for German Wikipedia articles that contain the generalized formula pattern for these sums with 1/π value:

https://de.wikipedia.org/wiki/Ramanujansche_g-Funktion_und_G-Funktion

https://de.wikipedia.org/wiki/Jacobische_Thetafunktion

https://de.wikipedia.org/wiki/Elliptische_Integrale

And please do the strg-f thing and enter the searching word Kreiszahl so that you are at the right positions of those articles! Please do it! This will help you. Because then you have many very good formulas. Have a nice time! Reformbenediktiner (talk) 20:09, 12 November 2024 (UTC)[reply]
