Deleng ing ngisor iki lan banjur njawab pitakonan ing basa sing padha: Passage: The series 1 − 2 + 3 − 4 +... is closely related to Grandi's series 1 − 1 + 1 − 1 +.... Euler treated these two as special cases of 1 − 2n + 3n − 4n +... for arbitrary n, a line of research extending his work on the Basel problem and leading towards the functional equations of what are now known as the Dirichlet eta function and the Riemann zeta function. Pitakonan: apa loro fungsi sing teka saka karya ing masalah Basel?
fungsi eta Dirichlet lan fungsi zeta Riemann
