Baselproblem

1. (mathematics) Thequestion as to thevalue of${\displaystyle \sum _{n=1}^{\mathrm{\infty }}\frac{1}{n^2}}$, thesum of thereciprocals of thesquares of thepositiveintegers.

     As noted, some of Euler's contemporaries, while accepting his answer to theBasel Problem, wondered about the validity of the argument that got him there.

     Solvingthe Basel problem was one of the early triumphs of L. Euler (1707–1783)... .

     And so ends one of Euler's most famous papers. We see that Euler actually solves theBasel problem three times and that he does much more.
