Summary
| Description |
English: The first 100,000 elements of the sequence (red line), where is the prime-counting function. Adrien-Marie Legendre conjectured in 1808 that this sequence would converge to a value of approximately 1.08366 (blue line), which became known as Legendre's constant. The actual limit was later shown to be exactly 1.
Français : En rouge, les 100 000 premiers termes de la suite , où est la fonction de compte des nombres premiers. Adrien-Marie Legendre a conjecturé en 1808 que cette suite converge vers un nombre valant approximativement 1,08366 (en bleu), qui est devenu la Constante de Legendre. Il a été prouvé plus tard que la limite exacte est 1. |
