Isibaxo - egopheni

Ukwakheka zejiyometri, leyo ibizwa ngokuba hyperbola, - egopheni omthebelele mzobo bolwesibini ezibandakanya ezigoso ezimbini ethathelwe ngaphandle kwaye musa ayangenana. Le ndlela yokubala izibalo ukuze achaze oko ngolu hlobo lulandelayo: y = k / x, ukuba inani phantsi isalathisi k akalingani zero. Ngamanye amazwi, encotsheni curve basoloko ezama ukuba zero, kodwa uya wawela kunye naye. Ukususela isikhundla kwinqanaba yokwakha isibaxo - isixa lamanqaku-moya. ingongoma nganye enjalo iphawulwa kumgama rhoqo ukusuka modulus umahluko iingongoma ezimbini focal.

igophe Flat ukwahlula iimpawu ezisisiseko ikhona kuphela kuye,

• Isibaxo - ezi imigca emibini eyahlukeneyo ngokuthi amasebe.
• Embindini kukho axis kubutha enkulu ke embindini mzobo.
• Lokuceba ibizwa enye ecaleni kwenye phantsi kwamasebe amabini.
• ubude Focal umgama ukusuka kwigophe ukuya kumbindi enye nakujoliso olutsha (zibonakaliswe 'c' incwadi).
• isibaxo axis Uninzi ichaza umgama imfutshane phakathi kwamasebe-imigca.
• bubuxoki nakujoliso olutsha kwi axis ezinkulu, ngaphandle umgama elifanayo ukusuka embindini curve. Line, ezixhasa axis enkulu, ebizwa esqwini ezinqamlezayo.
• axis semi-ezinkulu - ngumgama abaliweyo ukusuka embindini kwigophe ukuya kwenye iincopho (eboniswe unobumba "a").
• Umgca othe ngqo ukwandisa perpendicularly ukuya iasi enqamlezileyo ngokusebenzisa iziko layo, ebizwa esqwini udibaniso.
• parameter Focal ichaza lekhefu phakathi ujoliso kunye isibaxo ukuba aa Incopho axis yayo enqamlezileyo.
• Umgama phakathi ujoliso kunye asymptote kuthiwa ifuthe parameter kwaye idla ukuyifunda iifomyula phantsi unobumba «b».

Xa we cartesian yesiqhelo equation esaziwa apho ukwakhiwa ukuze hyperbola Kubonakala ngathi: (x ^2/2) - (y ² / b ²⁾ = 1. Uhlobo curve into efanayo isiqingatha-line kuthiwa alinganayo. Xa engunxantathu nokulungelelanisa inkqubo, unako ukuchaza equation elula: UX = a ^2/2, kunye nakujoliso olutsha lwe hyperbola kufuneka ingabekwa amanqaku ekudibaneni (a, a) kunye (-a, -a).

hyperbola curve nganye enxuseneyo anokubakho. Le nguqulelo yakhe udibaniso, apho nezamazembe lize, kunye asymptote sihlale phantsi emhlabeni. iimpawu Optical shape kukuba kukho umthombo wokukhanya wentelekelelo ugxininiso isebe yesibini uyakwazi ziboniswe kwaye iphazamise kwi yesibini ingqwalasela. Nayiphi na ingongoma izakhono hyperbola inobudlelwane rhoqo ukuya ugxininiso umgama ukuya nayiphi na umgama ukusuka directrix. igophe lohlobo flat unakho ukubonisa zombini esipilini yomgca ojikelezayo xa ijikelezwe ngokusebenzisa 180 ° phakathi.

Le eyinqaba le hyperbola uchazwa iimpawu wokwamanani licandelo ku gqiba nge, apho icandelo cross ibonisa iqondo ukutenxa kwisangqa esigqibeleleyo. Xa iifomyula zemathematika, inani eboniswe unobumba "e". Eyinqaba invariant ngokubanzi ngokuphathelele kwi-moya intshukumo kunye nenkqubo utshintshwano yayo kufana. Hyperbola - umfanekiso apho eyinqaba usoloko ulingana umlinganiselo phakathi ubude kunye esqwini ezinkulu.
