Txhua tus lej tuaj yeem suav tau (tshaj tus lej tiag) rau hauv cov khoom ntawm cov khoom sib xws thiab cov xwm txheej tsis txaus ntseeg. Lub Ntsiab Tseem Ceeb ntawm Algebra yog thawj zaug ua pov thawj los ntawm Carl Friedrich Gauss (1777-1855).

Yuav ua li cas polynomials tsis tuaj yeem suav tau?

A polynomial nrog tus lej coefficients uas tsis tuaj yeem ua rau hauv ntau lub npe ntawm qib qis, kuj nrog cov lej sib npaug, hu ua irreducible lossis prime polynomial.

Puas yog txhua tus lej muaj feem cuam tshuam?

Kev qhia ntau yam yuav tsuas yog qhov cuam tshuam yog tias nws hla lossis kov X-axis. Nco ntsoov, txawm li cas los xij, yog tias koj tuaj yeem siv Complex (hu ua "kev xav") cov lej ces txhua tus lej yog qhov ua tau zoo.

Puas tau tag nrho cov polynomials ua ke?

Koj tuaj yeem ua ke txhua lub npe hauv x raws li peb tau pom. Koj tuaj yeem koom ua ke txhua tus lej hauv sine thiab cosines los ntawm kev hloov nws mus rau hauv cov lej ntawm sines thiab cosines ntawm cov lus sib txawv uas siv cov kab lus rau lawv nyob rau hauv cov nqe lus ntawm complex exponentials.

Dab tsi yog qhov derivative ntawm polynomial?

Polynomials yog qee qhov haujlwm yooj yim tshaj peb siv. Peb yuav tsum paub cov derivatives ntawm polynomials xws li x 4+ 3 x, 8 x 2+ 3x + 6, thiab 2. Cia peb pib nrog qhov yooj yim tshaj ntawm cov no, cov haujlwm y=f (x)=c, qhov twg c yog qhov tsis tu ncua, xws li 2, 15.4, lossis ib lab thiab plaub (10 6 +4).
