Baca bagian di handap ieu, tuluy ngajawab patarosan dina basa nu sarua jeung bagian: 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. Pertanyaan: Naon dua fungsi anu asalna tina gawé dina masalah Basel?
fungsi eta Dirichlet jeung fungsi zeta Riemann
