A vector yog txhua qhov ntau, xws li lub zog, uas muaj qhov loj (ntau) thiab kev taw qhia. Yog tias cov duab tsim ib daim duab peb sab, koj tuaj yeem siv Pythagorean Theorem thiab cov trigonometric ua haujlwm sine, cosine, thiab tangent los nrhiav qhov loj thiab kev taw qhia ntawm qhov tshwm sim.
Yog li ntawd, dab tsi yog daim ntawv ntawm lub vector?
Cov cov duab tus txheej txheem txoj hauj lwm muaj nws pib nyob rau hauv keeb kwm. Cov daim ntawv ntawm ib vector yog tus txiav txim khub uas piav qhia txog kev hloov pauv hauv x- thiab y-tus nqi. Ob cov duab yog sib npaug yog tias lawv muaj tib qhov loj thiab kev taw qhia. Lawv yog parallel yog tias lawv muaj tib yam lossis oppositedirection.
Tsis tas li ntawd, piv txwv vector yog dab tsi? Piv txwv ntawm cov khoom xws li kev ncua deb, kev txav chaw, nrawm, nrawm, nrawm, quab yuam, huab hwm coj, lub zog, lub zog, ua haujlwm, lub zog, thiab lwm yam. vector quantity yog ib qhov ntau uas tau piav qhia tag nrho los ntawm ob qho tib si qhov loj thiab kev taw qhia.
Ntawm no, dab tsi yog vector nyob rau hauv tus qauv txoj hauj lwm?
A txheem vector yog a vector nyob rau hauv tus qauv , uas txhais tau tias a vector nrog thawj taw tes ntawm keeb kwm nyob rau hauv lub Cartesian coordinate system. Txhua vector nyob rau hauv lub dav hlau yog sib npaug rau a txheem vector . Displacement yog ib qho piv txwv ntawm qhov ntsuas los ntawm a vector.
Dab tsi yog qhov txawv ntawm ib txoj kab hluav taws xob thiab vector?
Vector thiab ray yog symbolized tib yam: ib kab segment nrog ib tug xub ntawm ib kawg tab sis lawv yog heev txawv yam. Vector yuav zoo li no: A ray tsuas muaj ib qho kev taw qhia thiab qhov pib, thiab nws muaj infinitelength. A ray yuav zoo li pib qhov twg koj nyob tam sim no hauv kev taw qhia sab qab teb-sab hnub tuaj.

Dab tsi yog vector hauv Matrix?
Scalars, Vectors thiab Matrices A scalar yog tus lej, xws li 3, -5, 0.368, thiab lwm yam, Avector yog cov npe ntawm cov lej (yuav ua tau ib kab lossis kab), Amatrix yog ib qho ntawm cov lej (ib lossis ntau kab, ib lossis ntau kab)
Dab tsi yog txoj hauv kev yooj yim tshaj plaws los kawm trigonometry?
Kawm Trigonometry hauv 5 kauj ruam Kauj Ruam 1: Tshawb xyuas koj txhua yam hauv paus. Kauj Ruam 2: Pib nrog lub kaum sab xis daim duab peb sab. Piv txwv li: Lub kaum sab xis muaj ob sab 5 cm thiab 3 cm pom lub hypotenuse. Siv Pythagoras theorem. Kauj Ruam 4: Kawm lwm yam tseem ceeb ntawm trigonometry. Kauj Ruam 5: Kev xyaum yog tus yuam sij rau txhua ceg ntawm kev ua lej
Dab tsi yog qhov tseeb vector thiab txheeb ze vector?
Thaum siv cov vector tiag tiag, tus kheej lub nkoj thiab lwm lub nkoj txav ntawm lawv qhov tseeb ceev thiab cov chav kawm. Cov vectors tseeb tuaj yeem paub qhov txawv ntawm cov hom phiaj txav mus thiab nyob ruaj khov. Cov txheeb ze vector pab nrhiav cov nkoj ntawm kev sib tsoo. Lub nkoj uas nws vector hla dhau ntawm tus kheej lub nkoj txoj haujlwm yog nyob rau hauv kev sib tsoo
Dab tsi yog vector nyob rau hauv tus qauv txoj hauj lwm?
Ib tug qauv vector yog vector nyob rau hauv standardposition, uas txhais tau hais tias ib tug vector nrog pib taw tes ntawm lub hauv paus nyob rau hauv lub Cartesian coordinate system. Txhua vector nyob rau hauv lub dav hlau yog sib npaug rau tus qauv vector. Displacement yog ib qho piv txwv ntawm qhov ntsuas los ntawm avector
Dab tsi yog vector thiab scalar hauv physics?
Qhov ntau yog ib qho vector lossis scalar. Ob pawg no tuaj yeem paub qhov txawv ntawm ib leeg los ntawm lawv cov ntsiab lus sib txawv: Scalars yog qhov ntau uas tau piav qhia tag nrho los ntawm qhov loj (lossis tus nqi lej) ib leeg. Vectors yog qhov ntau uas tau piav qhia tag nrho los ntawm qhov loj thiab qhov taw qhia
