Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Mumwe we14th century Oxford Calculators, William Heytesbury, achishaya differential calculus uye pfungwa yemiganhu, akakurudzira kuyera kumhanya kwechinguva "nenzira yaizotsanangurwa ne [muviri] kana... yaifambiswa zvakaenzana padanho rakaenzana rekumhanya kwainofambiswa panguva iyoyo yakapihwa".Heytesbury nevamwe vakaona masvomhu daro rakafukidzwa nemuviri uri pasi pekufamba kwakaringana kwakakurumidza (nhasi rakagadziriswa nekubatanidzwa), vachiti "muviri unofamba zvakaenzana kuwana kana kurasikirwa kuti kuwedzera [kwekumhanya] kuchapfuura mune imwe nguva yakapihwa [kure] zvakaenzana zvachose neicho chaizopfuura kana chaifamba chichienderera kuburikidza nenguva imwechete ine avhareji degree [yekumhanya]".Nicole Oresme paYunivhesiti yeParis neItaly Giovanni di Casali vakazvimiririra vakapa kuratidzwa kwemifananidzo yehukama iyi, vachiti nzvimbo iri pasi pemutsetse inoratidzira kumhanyisa kusingaperi, inomiririra chinhambwe chakarongwa. Mune imwe tsananguro yemasvomhu yakazotevera yeEuclid's Elements, Oresme akaita ongororo yakadzama zvikuru umo akaratidza kuti muviri uchawana mukuwedzera kwega kwega kwega kwenguva kuwedzera kwechero hunhu hunowedzera sehuwandu husina kuenzana. Sezvo Euclid akanga aratidza kuti uwandu hwezviverengero zvisingaverengeki ndihwo huwandu hwezvikamu zviviri, unhu hwose hunowanwa nomuviri hunowedzera sezvikamu zviviri zvenguva.  Mubvunzo: William Heytesbury aifanira kuitei pasina kuedza kuyera kumhanya kwechinguvana?
