Ib array yog ib pawg ntawm cov duab teem nyob rau hauv kab thiab kab. Kab khiav laug thiab sab xis thiab kab nce mus thiab nqis. Koj tuaj yeem sau ib kev sib npaug kev sib npaug los ntawm kev suav cov kab thiab kab. Array lej pab koj pom qhov tshwm sim thaum koj ntau.
Raws li, tus qauv array yog dab tsi?
A multiplication array tsuas yog ib qho kev npaj ntawm kab lossis kab uas phim a kev sib npaug kev sib npaug. Koj tuaj yeem ua arrays tawm ntawm cov khoom lossis cov duab, thiab koj tuaj yeem siv txhua hom duab.
Kuj Paub, qhov piv txwv ntawm ib qho array yog dab tsi? Rau piv txwv , lawv tuaj yeem pom cov tub ntxhais kawm nyob rau hauv ib qho kev taug kev uas tau teem rau hauv cov kab sib npaug lossis cov rooj zaum teeb tsa hauv kab hauv ib lub rooj sib tham. Cov kev npaj no txhua tus muaj qee yam sib xws; lawv tag nrho nyob rau hauv kab thiab kab. Ib qho kev npaj ntawm cov khoom, duab, lossis cov lej hauv kab thiab kab yog hu ua ib qho array.
Ua raws li qhov no, qhov piv txwv ntawm kab lus sib npaug yog dab tsi?
Ib feem ntawm a Multiplication kab lus Rau piv txwv , hauv kab lus "2 x 8 = 16," qhov "2 x 8" yog kev qhia lej. Cov kev qhia lej tsis suav nrog cov lus teb, uas tseem hu ua cov khoom.
array formula yog dab tsi?
Ib array formula yog a qauv uas tuaj yeem ua ntau qhov kev suav ntawm ib lossis ntau yam khoom hauv ib qho array . Koj tuaj yeem xav txog ib qho array raws li ib kab lossis kem ntawm qhov tseem ceeb, lossis kev sib txuas ntawm kab thiab kab ntawm qhov muaj nuj nqis. Cov qauv array tuaj yeem rov qab tau ntau qhov txiaj ntsig, lossis ib qho txiaj ntsig.

Yuav ua li cas koj paub thaum twg yuav siv cov khoom los yog quotient txoj cai?
Kev faib ua haujlwm. Yog li, thaum twg koj pom kev sib faib ntawm ob txoj haujlwm, siv txoj cai khoom thiab nyob rau hauv rooj plaub ntawm kev faib siv txoj cai quotient. Yog tias muaj nuj nqi muaj ob qho kev sib faib thiab faib, tsuas yog siv ob txoj cai raws li. Yog tias koj pom qhov sib npaug dav nws yog ib yam zoo li, qhov twg yog qhov ua haujlwm ntawm ib leeg
Yuav ua li cas koj simplify rational expressions nrog multiplication?
Q thiab S tsis sib npaug 0. Kauj Ruam 1: Factor ob tus lej thiab tus lej. Kauj Ruam 2: Sau ua ib feem. Kauj Ruam 3: Ua kom yooj yim rau cov lus qhia kom meej. Kauj Ruam 4: Muab ntau yam tseem ceeb hauv tus lej thiab / lossis tus lej. Kauj Ruam 1: Factor ob tus lej thiab tus lej. Kauj Ruam 2: Sau ua ib feem
Thaum twg koj yuav tsum siv cov haujlwm series koj siv nws li cas?
Nws yog siv los txiav txim siab cov khoom ntawm ib qho kev hloov pauv, uas yog hlau A yuav hloov lwm cov hlau B hauv kev daws yog tias A siab dua hauv koob. Kev ua yeeb yam ntawm qee cov hlau ntau dua, teev nyob rau hauv qhov kev txiav txim qis ntawm reactivity
Yuav ua li cas tshwm sim rau ib tug ionic siv lead ua thaum lub zog siv?
Txawm hais tias ionic crystals tau tuav ua ke los ntawm electrostatic zog, cov ions tau sib cais thaum cov khoom yaj. Ions muaj zog txaus nyiam rau qhov kawg ntawm cov polar molecules uas muaj nqi rov qab rau cov ions
Thaum twg koj yuav tsum siv correlation thiab thaum twg koj yuav tsum siv yooj yim linear regression?
Regression feem ntau yog siv los tsim cov qauv / qhov sib npaug los kwv yees cov lus teb tseem ceeb, Y, los ntawm cov txheej txheem kwv yees (X) sib txawv. Kev sib raug zoo feem ntau yog siv los ua kom sai thiab ua kom luv luv cov kev taw qhia thiab lub zog ntawm kev sib raug zoo ntawm ib pawg ntawm 2 lossis ntau tus lej sib txawv
