Kev faib ua haujlwm.
Yog li, thaum twg koj pom kev sib faib ntawm ob txoj haujlwm, siv txoj cai khoom thiab thaum 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.
Ib yam li ib tug yuav nug, ua li cas koj paub thaum twg yuav siv txoj cai khoom?
Cov txoj cai khoom yog tias ob "qhov" ntawm qhov ua haujlwm tau muab faib ua ke, thiab cov saw hlau txoj cai yog tias lawv raug tsim. Piv txwv li, txhawm rau nrhiav qhov derivative ntawm f(x) = x² sin(x), koj siv txoj cai khoom , thiab nrhiav qhov derivative ntawm g(x) = sin(x²) koj siv txoj saw txoj cai . Pom qhov txawv?
Ib yam li ntawd, koj yuav ua li cas sib txawv ntawm cov khoom siv txoj cai? Cov txoj cai khoom yog siv thaum sib txawv ob txoj haujlwm uas tau muab faib ua ke. Qee zaum nws yuav ua tau yooj yim muab lawv tawm. Piv txwv: Sib txawv y = x2(x2 2 x + 3).
Cov neeg kuj nug, qhov txawv ntawm cov khoom cai thiab quotient txoj cai yog dab tsi?
Cov Txoj cai khoom hais tias derivative ntawm a khoom ntawm ob lub luag haujlwm yog thawj zaug ua haujlwm lub sijhawm ua haujlwm ntawm qhov ua haujlwm thib ob ntxiv rau qhov ua haujlwm thib ob lub sijhawm ua haujlwm ntawm thawj qhov haujlwm. Cov Txoj cai khoom yuav tsum tau siv thaum lub derivative ntawm lub quotient ntawm ob lub luag haujlwm yuav tsum tau ua.
Tus qauv rau kev cai khoom yog dab tsi?
Cov txoj cai khoom yog a qauv siv los nrhiav cov derivatives ntawm cov khoom ntawm ob los yog ntau dua functions. (uv)'=u'v+uv'. Δ(uv)=u(x+Δx)v(x+Δx)−u(x)v(x). qhov twg Δu thiab Δv yog qhov nce ntxiv, feem, ntawm cov haujlwm u thiab v.

Koj siv cov khoom thiab txoj cai quotient li cas?
Txoj Cai Khoom Siv hais tias cov khoom siv ntawm ob lub luag haujlwm yog thawj zaug ua haujlwm ntawm qhov ua haujlwm thib ob ntxiv rau qhov ua haujlwm thib ob lub sijhawm ua haujlwm ntawm thawj zaug. Txoj Cai Khoom Muag yuav tsum tau siv thaum lub derivative ntawm quotient ntawm ob lub luag haujlwm yuav tsum raug coj los siv
Yuav ua li cas koj hloov txoj cai quotient rau cov cai khoom?
Txoj cai quotient tuaj yeem pom raws li kev siv ntawm cov khoom thiab cov kev cai saw hlau. Yog Q(x) = f(x)/g(x), ces Q(x) = f(x) * 1/(g(x)). Koj tuaj yeem siv txoj cai khoom kom sib txawv Q(x), thiab 1/(g(x)) tuaj yeem sib txawv siv txoj cai saw nrog u = g(x), thiab 1/(g(x)) = 1/u
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
Koj tuaj yeem siv txoj cai khoom siv tsis yog txoj cai quotient?
Muaj ob qhov laj thawj vim li cas txoj cai quotient tuaj yeem ua tau zoo dua rau txoj cai tswj hwm lub zog ntxiv rau cov khoom lag luam hauv kev sib txawv ntawm cov quotient: Nws khaws cov denominators thaum simplifying qhov tshwm sim. Yog tias koj siv txoj cai fais fab ntxiv rau cov khoom siv, feem ntau koj yuav tsum nrhiav ib tus lej sib piv kom yooj yim rau qhov tshwm sim
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
