A qhov system ntawm equations yog hu ua ib qhov system tsis sib xws ntawm equations yog tsis muaj kev daws vim hais tias cov kab yog parallel. A nyob qhov system ntawm equations yog thaum tib kab yog sau nyob rau hauv ob hom sib txawv kom muaj infinite daws.

Yog li ntawd, yog dab tsi yog ib tug nyob system?

nyob qhov system : A qhov system ntawm linear equations nyob rau hauv uas ob equations sawv cev rau. tib kab; muaj ib tug infinite cov kev daws rau ib nyob qhov system . tsis sib xws qhov system : A qhov system ntawm linear equations uas tsis muaj kev daws teeb meem vim lawv. sawv cev rau cov kab sib txuas, uas tsis muaj qhov taw tes lossis kab hauv ib qho.

Ib yam li ntawd, txhais tau li cas los ntawm qhov tsis sib xws thiab tsis sib xws? Teb: Zoo ib yam = kab sib tshuam ntawm qhov taw tes uas sawv cev rau qhov kev daws teeb meem tshwj xeeb ntawm cov kab ke ntawm kab sib npaug hauv ob qhov sib txawv. Algebraically, yog tias, cov kab zauv sib npaug 'pab yog zoo ib yam . Tsis sib haum = kab uas yog parralel tsis sib xws.

Raws li kev sib raug zoo, dab tsi yog qhov tsis sib xws linear system?

Ua raws li thiab Inconsistent Linear Systems . A qhov system ntawm kab tawm equations yog ib txheej ntawm kab tawm kev sib npaug uas yuav tsum tau daws ua ke. Qhov ntawd txhais tau tias cov qhov system ntawm qhov sib npaug lawv sawv cev tsis muaj kev daws teeb meem. A qhov system uas tsis muaj kev daws teeb meem yog hu ua ib qhov system tsis sib xws.

Yuav ua li cas koj thiaj paub yog tias ib qho kev ywj pheej?

Yog tias ib qho kev sib raug zoo muaj ib qho kev daws teeb meem, nws yog ywj siab

  1. Yog hais tias ib tug zoo ib yam system muaj ib tug infinite cov kev daws, nws yog nyob ntawm seb. Thaum koj kos cov kab zauv, ob qho tib si sib npaug sawv cev tib kab.
  2. Yog tias qhov system tsis muaj kev daws teeb meem, nws tau hais tias tsis sib haum.
