Linear zokuhlela

Linear udweliso yenye kwamasebe ibalulekileyo kwimathematika, oluqhutywa isifundo iziseko ithiyori kwaye methodological imisebenzi ethile. Eli sebe kwemathematika sisetyenziswa ngokubanzi kwiminyaka yakutshanje kwiinkalo ezahlukeneyo zoqoqosho kunye nobugcisa, nto leyo indima lokugqibela idlalwa ucwangciso zemathematika kunye nokusetyenziswa kweenkqubo ukubala ezenzekelayo. Le yesebe inzululwazi eyayinikelwe nasekufundweni iimodeli noun yomgama. Okt iinkqubo yomgama zanikezelwa amanani. Kuba okokuqala kule kota yaphakanyiswa yi T. Koopmans ngo-1951. Isicwangciso ngeyona ndlela inenzuzo enkulu kumgca ngamnye yenkqubo kunxulumana ngokuzenzekelayo ne kwinqanaba ngexabiso eliphezulu, uqikelelo oko kukuthi, cala uzimisele.

iinkqubo yomgama: iindlela

Ngoncedo lwe njengobuchule iinkqubo yomgama ingasombululwa eziliqela iingxaki extremal ukuba zinxulunyaniswa kuqoqosho. Kulo mzekelo, ngokuqhelekileyo ekufuneka ukufumana amaxabiso egqithiseleyo eminye imisebenzi variable. Njengesiseko iinkqubo yomgama ichazwa isisombululo of quadratic yomgama nga kuguqulwa zibalo kunye nokungalingani. Olu hlobo lwenkqubo luphawulwa ngeyantlukwano ekuqulunqeni zemathematika, ulandelelwano kunye nokuzimisela inkqubo yokubala kunye nokuhlaziya ubhalo. Oku kusebenza:

- Ukuba kukho ingqiniseko zemathematika kunye nezithintelo lobuninzi phakathi iimeko bafunda kunye variables;

- Ukuba kukho imiba interchangeability ngenxa izibalo bokulandelelana;

- kwimeko ekuqiqeni lweMathematika edityaniswe ukuqonda kakuhle eli nesenzeko efundwayo.

iinkqubo yomgama kwi kwimveliso industrial kunegalelo ekubaleni ukusebenza ngokupheleleyo kuzo zonke oomatshini, imigca imveliso, oomatshini, kwakunye nesigqibo eyiyo yokusetyenziswa iingxaki ezikhoyo izinto.

Kwezolimo, xa usebenzisa le ndlela umiselwa ixabiso ubuncinane yokondla ekutyeni kunye nemali ekhoyo feed. Oku kuthatha ingqalelo iintlobo kunye nesiqulatho kwezondlo ezithile.

Kushishino Foundry ke, le ndlela ikuvumela ukuba ukufumana isisombululo kwingxaki zothutho kunye ingxaki kwimixube, ziyinxalenye intlawulo metallurgical. Undoqo ingxaki yezithuthi kulo mzekelo ibandakanya ufakelelo ilungileyo odlayo namashishini kumashishini ukuba bazibandakanya ekuvelisweni kweemveliso.

iinkqubo yomgama: ngxaki

A isici esasenza zonke iingxaki zoqoqosho leyo isonjululwe iindlela iinkqubo yomgama na ukhetho yokwahluka ezithile isigqibo, ngokunjalo nezinyanzelo. Ngenxa isicombululo kule ngxaki akakwazi ukufumana isisombululo kakuhle zonke iindlela.

Ixabiso elikhulu zokusetyenziswa ubuchule yomgama iinkqubo kuqoqosho kulukhetho na uhlobo ngokupheleleyo inani elikhulu iinketho ezijongwa kuvunyelwe kunokwenzeka. iingxaki ezinjalo nzima ukusombulula kwezinye iindlela, ngoko ngokukhawuleza njengoko kukuvumela ukuba ufumane iqondo indlela eyiyo yokusetyenziswa lobutyebi obuveliswayo. Ngoncedo iinkqubo yomgama kuvunyelwe ngoko umsebenzi inkulu izithuthi, ekufuneka zinciphise ukujika yemphahla yabathengi ngethuba lusenzelwa evela kumenzi.

iinkqubo yomgama ku Excel

Xa inkqubo yokusombulula le ngxaki ukuze aqale ukudala umfuziselo kubonisa kuqulunqo kweemeko ulwimi lwezibalo. Emva kweli nyathelo, unako ukufumana isisombululo ngokusebenzisa indlela graphic. Kukho i umsebenzi okhethekileyo "Khangela izisombululo" oku Excel.

Njengoko kucacile ukusuka ngasentla, iinkqubo yomgama i umda kakhulu ebanzi isicelo.
