Tsis yog, txhua txoj kab ncaj nraim tsis yog daim duab ntawm cov duab ua haujlwm ntawm kev ua haujlwm Ib qho algebraic nkhaus hauv Euclidean dav hlau yog cov ntsiab lus uas nws cov kev tswj xyuas yog cov kev daws teeb meem ntawm bivariate polynomial equation p (x, y)=0. Qhov kev sib npaug no feem ntau hu ua qhov sib npaug implicit ntawm qhov nkhaus, nyob rau hauv sib piv rau cov curves uas yog cov duab ntawm ib tug muaj nuj nqi defining meej y raws li ib tug muaj nuj nqi ntawm x. https://en.wikipedia.org › wiki › Algebraic_curve

. Yuav luag tag nrho cov kab sib npaug yog ua haujlwm vim tias lawv dhau qhov kev sim kab ntsug.Koj txiav txim siab li cas yog txoj kab ncaj nraim yog txoj haujlwm?
Kev ntsuas kab ntsug tuaj yeem siv los txiav txim siab seb daim duab puas sawv cev rau txoj haujlwm. Yog tias peb tuaj yeem kos ib txoj kab ntsug uas cuam tshuam ib daim duab ntau dua ib zaug, ces daim duab tsis txhais tau tias muaj nuj nqi vim tias ib qho kev ua haujlwm tsuas muaj ib qho txiaj ntsig rau txhua tus nqi nkag.
Puas kab kab rov tav muaj nuj nqi?
Yog. Nws sawv cev a muaj nuj nqi uas muab cov txiaj ntsig zoo ib yam txawm tias koj muab dab tsi tawm tswv yim. Feem ntau sau ua f(x)=a (yog li, piv txwv li, f(x)=5 yog ib qho haujlwm zoo li no), thiab hu ua qhov ua haujlwm tas li.
Puas yog kab ntsug muaj nuj nqi lossis kev sib raug zoo?
Yog tias kab ntsug hla cov duab hauv txhua qhov chaw ntawm ib qho taw tes, ces qhov kev sib raug zoo yog a muaj nuj nqi. Nov yog qee qhov piv txwv ntawm kev sib raug zoo uas tseem ua haujlwm vim lawv dhau qhov kev sim kab ntsug.
Vim li cas X A yog kab ntsug?
Vertical Lines
Ib yam nkaus, nyob rau hauv daim duab ntawm ib kab ntsug, x tsuas yog siv ib qho nqi. Yog li, qhov sib npaug ntawm kab ntsug yog x=a, qhov twg a yog tus nqi uas x siv.
