Kuj paub, muaj pes tsawg txoj kev daws teeb meem sib tshuam?
Qhov no txhais tau tias cov kab sib tshuam ntawm ib qho taw tes-y-intercept. Nco qab tias cov kab sib tshuam muaj ib xal thiab yog li ntawd qhov system zoo ib yam. Vim tias cov kab tsis zoo ib yam, cov kab sib npaug yog ywj siab.
Qhov thib ob, koj yuav qhia li cas yog tias lub kaw lus tsis muaj kev daws teeb meem? Yog ib yam zoo ib yam system muaj tus naj npawb ntawm infinite kev daws teeb meem , nws yog nyob. Thaum twg koj graph cov equations, ob qhov sib npaug sawv cev tib kab. Yog tias qhov system tsis muaj kev daws teeb meem , yog hais tias tsis sib haum. Cov graphs ntawm cov kab tsis sib tshuam, yog li cov graphs yog parallel thiab muaj tsis muaj tshuaj.
Tsuas yog li ntawd, muaj pes tsawg txoj kev daws teeb meem rau qhov system no?
Yuav muaj kev daws teeb meem xoom, 1 daws los yog kev daws teeb meem tsis kawg - txhua rooj plaub tau piav qhia hauv qab no. Nco tseg: Txawm hais tias cov kab ke ntawm cov kab sib npaug tuaj yeem muaj 3 lossis ntau qhov sib npaug, peb yuav xa mus rau cov xwm txheej feem ntau - lub qia nrog 2 kab.
Dab tsi yog ib qho kev sib npaug nrog cov kev daws teeb meem tsis kawg?
Kev daws qhov System of Equations los ntawm Hloov 0 = 0 Raws li koj pom peb muaj qhov sib npaug ntawm qhov qub. Qhov no txhais tau tias kev sib npaug muaj ib tsis kawg tus lej ntawm kev daws teeb meem . Siv ib qho nqi ntawm x thiab y uas daws ib qho kev sib npaug thiab cov txiaj ntsig zoo ib yam yuav daws qhov thib ob.
Pom zoo:
Muaj pes tsawg txoj kev daws teeb meem tib kab muaj?
Cov kab ke ntawm kab sib npaug tuaj yeem tsuas muaj 0, 1, lossis ib qho kev daws teeb meem tsis kawg. Ob kab no tsis tuaj yeem hla ob zaug. Cov lus teb raug yog tias qhov system muaj ib qho kev daws teeb meem
Yuav ua li cas koj thiaj paub yog tias tus nqi sib npaug tsis muaj kev daws teeb meem?
Tus nqi tiag tiag ntawm tus lej yog nws qhov kev ncua deb ntawm xoom. Tus lej ntawd yuav yog qhov zoo, vim koj tsis tuaj yeem ua tsis zoo ob txhais taw deb ntawm ib yam dab tsi. Yog li txhua tus nqi sib npaug sib npaug sib npaug rau tus lej tsis zoo yog tsis muaj kev daws teeb meem, txawm tias tus lej ntawd yog dab tsi
Koj yuav txiav txim siab li cas yog tias qhov tsis sib xws tsis muaj kev daws teeb meem?
Cais tawm tus nqi tseeb ntawm sab laug ntawm qhov tsis sib xws. Yog tias tus lej ntawm sab nraud ntawm qhov tsis sib xws yog qhov tsis zoo, koj qhov kev sib npaug tsis muaj kev daws teeb meem lossis tag nrho cov lej tiag tiag li kev daws teeb meem. Siv cov cim ntawm txhua sab ntawm koj qhov tsis sib xws los txiav txim siab qhov twg ntawm cov xwm txheej no tuav
Yuav ua li cas ib tug kab zauv muaj infinite kev daws teeb meem?
Ib txoj kab sib npaug muaj ntau qhov kev daws teeb meem tsis kawg (hauv qhov sib txawv x) yog tias thiab tsuas yog tias ob qho tag nrho cov coefficients ntawm x ntawm ob sab yog sib npaug, thiab tag nrho cov nyob ntawm ob sab yog sib npaug
Puas yog nws ua tau rau ib qho kev sib npaug ntawm ob txoj kab sib npaug kom tsis muaj kev daws teeb meem piav qhia koj qhov laj thawj?
Cov kab ke ntawm kab sib npaug tuaj yeem tsuas muaj 0, 1, lossis ib qho kev daws teeb meem tsis kawg. Ob kab no tsis tuaj yeem hla ob zaug. Cov lus teb raug yog tias qhov system muaj ib qho kev daws teeb meem.
