Ib qhov system kab sib npaug tuaj yeem ua tsis sib xws lossis sib xws nyob . Yog tias kab nyob rau hauv lub system muaj tib txoj kab nqes tab sis txawv intercepts ces lawv tsuas yog inconsistent. Txawm hais tias lawv muaj tib txoj kab nqes thiab cuam tshuam (hauv lwm lo lus, lawv yog tib txoj kab) ces lawv zoo ib yam nyob.

Tsis tas li ntawd, cov kab sib dhos puas tsis sib haum?

Yog tias kab yog parallel , lawv yuav tsis sib tshuam. Qhov ntawd txhais tau hais tias txoj kev sib npaug lawv sawv cev tsis muaj kev daws teeb meem. Ib qho system uas tsis muaj kev daws teeb meem yog hu ua ib qho tsis sib xws qhov system.

Tom qab ntawd, lo lus nug yog, ua li cas koj thiaj paub tias daim duab yog ywj siab los yog nyob ntawm? 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 xws li system muaj ib tug infinite cov kev daws teeb meem, 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.

Kuj paub yog, thaum cov kab sib npaug lawv yog?

Parallel kab yog coplanar kab (hauv tib lub dav hlau) uas tsis sib tshuam (tsis txhob hla ib leeg). Kab uas yog thaum uas tig mus muaj tib lub steepness (los yog tib lub kaum sab xis ntawm kab rov tav). Txij li thaum kab sib npaug muaj tib lub steepness, lawv muaj tib txoj kab nqes.

Lub ntsiab lus ntawm dependent linear equation yog dab tsi?

Ib qhov system kev sib npaug yog ob lossis ntau dua kev sib npaug uas daws ib txhij, thaum a nyob system ntawm linear equations yog kev sib npaug uas tsim ib txoj kab ncaj nraim ntawm ib daim duab. A nyob system ntawm linear equations muaj cov kev daws teeb meem tsis kawg.
