Yog lawm! Txij li txhua txhua polynomial ntawm degree mus txog 2 kuj yog polynomial ntawm degree mus txog 3, P2 yog subset ntawm P3 . Thiab peb twb paub lawm P2 yog vector space, ces nws yog a subspace ntawm P3 . Uas yog hais, R2 tsis yog ib tug subset ntawm R3.
Cov neeg kuj nug, yog cov txheej ntawm tag nrho cov polynomials ntawm degree 3 subspace ntawm p3?
1. P3 (F) yog tus qhov chaw vector ntawm tag nrho polynomials ntawm degree ≦ 3 thiab nrog coefficients hauv F. Qhov loj me yog 2 vim 1 thiab x yog linearly ywj siab polynomials uas span subspace , thiab yog li lawv yog lub hauv paus rau qhov no subspace . (b) Cia koj ua tus subset P3 (F) suav nrog tag nrho cov polynomials ntawm degree 3.
Dab tsi yog qhov subspace ntawm r3? Hais lus nruj me ntsis, A Subspace yog Vector Space nrog rau lwm qhov loj dua Vector Space. Yog li ntawd, tag nrho cov khoom ntawm Vector Space, xws li raug kaw nyob rau hauv ntxiv thiab scalar multiplication tseem muaj tseeb thaum siv rau lub Subspace . ex. Peb txhua tus paub R3 yog Vector Space.
Tib neeg kuj nug, dab tsi yog p2 hauv linear algebra?
Cia P2 ua qhov chaw ntawm polynomials ntawm degree ntau tshaj 2, thiab txhais cov kab tawm Kev hloov pauv T: P2 → R2 T(p(x)) = [p(0) p(1)] Piv txwv li T(x2 + 1) = [1 2].
Zero polynomial yog dab tsi?
Zero Polynomial . Qhov tsis tu ncua polynomial . nws cov coefficients tag nrho yog sib npaug rau 0. Qhov sib thooj polynomial muaj nuj nqi yog qhov ua haujlwm tas li nrog tus nqi 0, tseem hu ua xoom daim ntawv qhia. Cov xoom polynomial yog tus additive tus kheej ntawm cov additive pab pawg neeg ntawm polynomials.

2) Lub teeb yog cais raws li Electromabnerle RADIATION vim hluav taws xob thiab sib nqus teb vibrate nyob rau hauv lub teeb yoj. RADIANT ENERGY - yog lub zog uas taug kev los ntawm hluav taws xob. Ib qho piv txwv ntawm qhov no yog lub teeb. 4) Cov hluav taws xob cua sov, tseem hu ua _INFRARED WAVES w tsis tuaj yeem pom ntawm koj lub qhov muag tab sis tuaj yeem hnov ntawm koj cov tawv nqaij
Koj nrhiav tau lub subspace li cas?
VIDEO Tsis tas li ntawd, puas yog lub hauv paus ntawm subspace? Peb yav tas los txhais a hauv paus rau a subspace raws li qhov tsawg kawg nkaus ntawm vectors uas spans subspace . Qhov ntawd yog, ib lub hauv paus rau k-dimensional subspace yog ib txheej ntawm k vectors uas span lub subspace .
Puas yog ib qho ntawm cov kev ntsuas ntawm dispersion ntawm qhov ntau?
Cov kev ntsuas ntawm lub hauv paus nyiam tsis txaus piav qhia cov ntaub ntawv. Yog li piav qhia cov ntaub ntawv, ib tus yuav tsum paub qhov txawv ntawm qhov sib txawv. Qhov no yog muab los ntawm kev ntsuas ntawm dispersion. Range, interquartile ntau yam, thiab tus qauv sib txawv yog peb qhov kev ntsuas feem ntau ntawm kev sib cais
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Koj ua pov thawj li cas matrix yog subspace?
Lub Centralizer ntawm Matrix yog Subspace Cia V yog qhov chaw vector ntawm n × n matrices, thiab M∈V ib lub matrix ruaj khov. Txhais W={A∈V∣AM=MA}. Lub teeb W ntawm no yog hu ua centralizer ntawm M hauv V. Ua pov thawj tias W yog ib qho subspace ntawm V
