Duba wurin da ke ƙasa sannan ka amsa tambayar daga baya a cikin harshe ɗaya kamar yadda wurin yake:  Passage: Euler ya gabatar da kuma yaduwa da dama na al'ada ta hanyar litattafansa da yawa da kuma rarraba littattafai. Mafi mahimmanci, ya gabatar da ma'anar aiki kuma shine farkon wanda ya rubuta f ((x) don nuna aikin f da aka yi amfani da shi ga hujja x. Ya kuma gabatar da alamun zamani don ayyukan trigonometric, harafin e don tushen logarithm na halitta (wanda yanzu aka sani da lambar Euler), harafin Girkanci Σ don tarawa da harafin i don nuna ma'aunin tunanin. Yin amfani da harafin Girkanci π don nuna rabo daga kewayon da'irar zuwa diamita shi ma Euler ya shahara, kodayake ya samo asali ne daga masanin lissafi na Welsh William Jones.
