• 17:0617:06, 21 December 2019diff hist +2,777‎ Basel problem‎ Deacon Vorbis, I think you did not read the references carefully enough. The proof that I add is exactly the proof published by Euler. I just rewrote it using modern mathematical tools so that readers can understand it more easily and skip certain details that would seem tedious nowadays. I did not write that it is Euler's proof. I just wrote one historical fact : Euler published this proof. Please mention sources on the talk page to prove what you assert.Tag: Visual edit
• 13:2913:29, 21 December 2019diff hist +2,738‎ Basel problem‎ Mabye I was not clear before. We I said "almost the same", I was comparing Euler's second proof and the proof that I added. I was not comparing Euler's first proof and Euler's second proof. Euler's second proof and Euler first proof are not "almost the same". They are completely different. So I am not reproducing a proof which is already in the page. Now I add Euler's second proof, not a proof that is almost the same as Euler's second proof.Tag: Visual edit

• 22:4022:40, 20 December 2019diff hist +2,768‎ Basel problem‎ I added my previous work with one more reference. I mentionned a historical fact proved by the references. I regret that the user Deacon Vorbis deleted my previous work in less than 24 hours. Indeed, he gave me incentives to discuss on the talk page, but he has not replied to the comments I published on that page for two weeks.Tags: Visual edit Mobile edit Mobile web edit

• 16:1116:11, 6 December 2019diff hist +1,864‎ Basel problem‎ I mentionned the source of the proof this time. The source is the French page of the same wikipedia article. The latter refer to French sources (L. Euler, « Démonstration de la somme de cette suite 1 + 1/4 + 1/9 + 1/16 + 1/25 + 1/36 + etc. », Journal lit. d'Allemagne, de Suisse et du Nord, vol. 2,‎ 1743, p. 115-127 (lire en ligne [archive]) (E63, Opera Omnia, I.14, p. 177-186), écrit en 1741.
