Cov SUV Kev sib npaug yog siv thaum acceleration tsis tu ncua thiab tshaj tawm hloov. Yog tias qhov ceev tsis tu ncua, koj tuaj yeem ua tau siv qhov ceev, nrug thiab sij hawm daim duab peb sab. Lawv tuaj yeem siv los ua haujlwm tawm qhov pib thiab qhov kawg ceev, lub sijhawm, kev tawg thiab kev nrawm, yog tias tsawg kawg yog peb qhov ntau. paub.
Xav txog qhov no, dab tsi yog 5 suvat equations?
Lawv hu ua SUVAT sib npaug vim tias lawv muaj cov hauv qab no sib txawv: s - nrug, u - pib nrawm ,v- nrawm lub sijhawm t, a - kev ceev thiab lub sijhawm.
Ib sab saum toj, suvat yog dab tsi? Cov SUV equations yog kinematics equations nyob rau hauv physics rau motion nyob rau hauv tas li acceleration. Txhua tsab ntawv ntawm SUV sawv cev rau ntau qhov sib txawv raws li hauv qab no: S: tshem tawm. U: pib tshaj tawm. V: kawg velocity.
Ib yam li ib tug yuav nug, yog V pib lossis qhov kawg tshaj tawm?
Pib Velocity Formula. Kev nrawm yog tus nqi uas qhov chaw ntawm ib qho khoom hloov pauv mus rau lub sijhawm. Cov pib tshaj tawm , v i yog cov nrawm ntawm cov khoom ua ntej acceleration ua rau muaj kev hloov. Tom qab nrawm rau qee lub sijhawm, qhov tshiab nrawm yog cov qhov kawg ceev , v f.
Yuav ua li cas koj nrhiav tau nro nyob rau hauv ib txoj hlua?
Cov nruj nyob rau hauv ib tug muab strand ntawm txoj hlua los yog txoj hlua yog qhov tshwm sim ntawm cov quab yuam rub ntawm txoj hlua los ntawm qhov kawg. Raws li kev ceeb toom, quab yuam = huab hwm coj × acceleration. Piv txwv tias txoj hlua yog ncab kom nruj, txhua qhov kev hloov pauv hauv kev nrawm lossis loj hauv cov khoom uas txoj hlua txhawb nqa yuav ua rau muaj kev hloov pauv hauv nruj hauv txoj hlua.

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 paub thaum twg yuav siv brackets los yog parentheses interval notation?
Nws yog ib hom kev sau ntawv uas sawv cev rau qhov nruab nrab nrog ib khub ntawm tus lej. Cov kab lus thiab cov brackets yog siv los qhia seb puas yog ib qho ntsiab lus tsis suav nrog. Ib qho kev sib dhos yog siv thaum lub ntsiab lus lossis qhov muaj nuj nqis tsis suav nrog hauv lub sijhawm, thiab siv lub bracket thaum tus nqi suav nrog
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
Koj paub li cas thaum siv Sohcahtoa?
Kev suav tsuas yog ib sab ntawm txoj cai kaum sab xis muab faib los ntawm lwm sab peb tsuas yog yuav tsum paub sab twg, thiab qhov ntawd yog qhov uas 'sohcahtoa' pab. Sine, Cosine thiab Tangent. Sine: soh sin(θ) = opposite / hypotenuse Tangent: toa tan(θ) = opposite / adjacent
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
