Jirgin sama da girma uku
Tsarin farko shine lissafin jirgin sama. Lissafin jirgin sama shine yin nazarin tsarin geometric da abubuwan aunawa (yanki, tsayi, kusurwa) na layuka madaidaiciya da masu lankwasa kwano biyu (ma'ana, sassan conic, wadanda suke ellipses, hyperbolas, da parabolas) a jirgin. Jirgin saman sama yana daukar hanyoyin axiomatic, wanda ke da mahimmancin gaske a tarihin tunanin lissafi.
Abubuwan da ke tattare da yanayin jirgi shima yana canzawa zuwa yanayi mai kyau na yanayi mai girma uku. Don ƙididdige ƙarar da yanki, hakika mutane sun fara shigar da asalin asalin lissafi.
Bayan da Descartes ya gabatar da tsarin daidaitawa, alakar dake tsakanin aljabara da lissafi ta kara bayyana kuma kusa. Wannan ya haifar da ƙirƙirar ilimin lissafi. Descartes da Fermat ne suka kirkiro lissafin nazari. Wannan wani lamari ne mai ban mamaki. Daga mahangar nazarin lissafi, kadarorin adadi na lissafin lissafi za a iya danganta su da kayan bincike da aljebra na lissafin lissafi. Matsalar rabe-raben siffofi na lissafi (alal misali, rarraba sassan kwalliya zuwa gida uku) ya rikida zuwa matsalar rarrabuwa da siffofin algebraic na lissafin, wato, matsalar neman masu canza aljebra.
