Ka kōrero ki te whiti i raro nei, kātahi ka whakautu i te pātai i muri mai i te reo kotahi ki te whiti: Passage: Euler introduced and popularized several notational conventions through his numerous and widely circulated textbooks. Ko te mea tino nui, i whakaurua e ia te ariā o te taumahi, a ko te tuatahi ki te tuhituhi f (x) ki te tohu i te taumahi f whakamahia ki te tautohe x. I whakaurua hoki e ia te tohu hou mō ngā taumahi trigonometric, te reta e mo te turanga o te logarithm tūturu (i teie nei hoki e mohiotia ana ko te tau o Euler), te reta Kariki Σ mō ngā whakarāpopototanga me te reta i ki te tohu i te wae whakaaro. Ko te whakamahinga o te reta Kariki π ki te tohu i te ōwehenga o te porowhita o te porowhita ki tona diameter i rongonui hoki e Euler, ahakoa i puta mai i te kaitarau Welsh William Jones. Pātai: Ko wai i rongonui i nga tikanga tikanga?
