Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Euler akazivisa uye akaita kuti zvizivikanwe nemagungano anoverengeka ezvinyorwa kuburikidza nemabhuku ake akawanda uye akaparadzirwa zvikuru. Zvikurukuru, akaunza pfungwa yebasa uye akanga ari wokutanga kunyora f ((x) kuratidza basa f rinoshandiswa pakukakavadzana x. Akaunzawo chiratidzo chemazuva ano chemabasa e trigonometric, tsamba ye e nokuda kwechigadziko che logarithm yomuzvarirwo (zvino inozivikanwawo sechiverengero chaEuler), tsamba yechiGiriki Σ nokuda kwokupfupikisa uye tsamba i kuratidza chinenge chiri chinhu. Kushandiswa kwetsamba yechiGiriki π kunoratidza chiyero chedenderedzwa redenderedzwa nedhaimita yaro kwakaitwawo kuti kuzivikanwe naEuler, kunyange zvazvo kwakatangira kumuWelsh wemasvomhu William Jones.  Mubvunzo: Ndiani akaita kuti tsika dzokufungidzira dzizivikanwe?
