Rau ntau radicals , koj tuaj yeem siv cov khoom vaj khoom tsev ntawm square keeb kwm rau ntau cov ntsiab lus ntawm txhua tus radical ua ke. Tom qab ntawd, nws tsuas yog ib qho teeb meem ntawm simplifying! Hauv qhov kev qhia no, koj yuav pom yuav ua li cas ntau ob radicals ua ke thiab ces simplify lawv cov khoom. Tshawb xyuas!
Raws li, koj tuaj yeem muab faib ua ob lub hauv paus?
Nco ntsoov tias cov keeb kwm yog tib yam- koj tuaj yeem ua ke square keeb kwm nrog square keeb kwm , orcub keeb kwm s kub keeb kwm , piv txwv. Tab sis koj tuaj yeem 't ntau ib square hauv paus i kub hauv paus siv txoj cai no. Nrhiav cov squares zoo meej hauv theradicand, thiab rov sau cov radicand ua cov khoom ntawm ob yam.
Tsis tas li ntawd, koj yuav faib thiab faib cov radicals li cas? LUS TEB: Siv cov khoom faib rau ntau . Tsis muaj cov ntsiab lus zoo li yuav tsum tau ua ke. Kev faib tawm radicals : Thaum twg faib cov radicals (nrog rau qhov ntsuas qhov sib npaug), faib hauv qab radical , thiab tom qab ntawd faib nyob rau hauv pem hauv ntej ntawm radical ( faib xijpeem multiplied lub sij hawm radicals ).
Ib yam li ntawd, yuav ua li cas koj faib cov hauv paus hniav?
Txoj Kev 2 Multiplying Square Roots WithCoefficients
- Muab cov coefficients. Ib tug coefficient yog ib tug lej nyob rau hauv pem hauv ntej ntawm lub radical kos npe.
- Ntxiv cov radicans.
- Qhia tawm ib qho zoo meej squares hauv radicand, yog tias ua tau.
- Muab lub hauv paus square ntawm lub zoo meej square los ntawm cov coefficient.
Koj yuav muab ntau npaum li cas?
Multiplication thiab Composition of Functions
- Txhawm rau muab ntau txoj haujlwm los ntawm scalar, muab txhua qhov tso zis los ntawm qhov ntsuas.
- Thaum peb coj f (g(x)), peb muab g(x) raws li cov tswv yim ntawm kev ua haujlwm f.
- Piv txwv li, yog f (x) = 10x thiab g(x) = x + 1, ces nrhiav f(g(4)), peb nrhiav g(4) = 4 + 1 + 5, thiab ces ntsuas f (5) = 10(5) = 50.

Yuav ua li cas koj txiav txim siab yog hais tias ib tug muaj nuj nqi muaj ib tug kab rov tav tangent?
Kab rov tav kab muaj txoj kab nqes ntawm xoom. Yog li ntawd, thaum lub derivative yog xoom, cov kab tangent yog kab rov tav. Txhawm rau nrhiav cov kab kab rov tav tangent, siv qhov derivative ntawm txoj haujlwm los nrhiav qhov xoom thiab ntsaws lawv rov qab rau hauv qhov sib npaug qub
Yuav ua li cas koj hloov ib tug muaj nuj nqi rau hauv vertex daim ntawv?
Txhawm rau hloov lub quadratic los ntawm y = ax2 + bx + c daim ntawv rau vertex daim ntawv, y = a(x - h) 2 + k, koj siv cov txheej txheem ua kom tiav cov square. Cia peb saib ib qho piv txwv. Hloov y = 2x2 - 4x + 5 rau hauv daim ntawv vertex, thiab hais lub vertex. y = ax2 + bx + c form
Yuav ua li cas koj pom ib tug nyob rau hauv ib tug quadratic muaj nuj nqi?
Qhov kev ua haujlwm quadratic f(x) = a(x -h)2 + k, tsis sib npaug rau xoom, yog hais tias nyob rau hauv cov qauv. Yog tias qhov zoo, daim duab qhib rau sab saud, thiab yog tias qhov tsis zoo, ces nws qhib downward. Txoj kab ntawm symmetry yog txoj kab x = h, thiab vertex yog qhov taw tes (h, k)
Yuav ua li cas koj thiaj nrhiav tau tus nqi siab tshaj plaws ntawm lub quadratic muaj nuj nqi?
Yog tias koj tau txais cov mis y = ax2 + bx + c, ces koj tuaj yeem pom tus nqi siab tshaj plaws uas siv cov mis max = c- (b2 / 4a). Yog tias koj muaj qhov sib npaug y = a (x-h) 2 + k thiab theatrem tsis zoo, ces qhov siab tshaj plaws yog k
Yuav ua li cas koj thiaj paub tias muaj nuj nqi yog lub zog muaj nuj nqi?
VIDEO Ib yam li ntawd, tib neeg nug, dab tsi ua rau lub zog ua haujlwm? A lub zog ua haujlwm yog a muaj nuj nqi qhov twg y = x ^n qhov twg n yog tus lej tiag tiag. Ntau tus niam txiv muaj nuj nqi xws li linear muaj nuj nqi thiab quadratic muaj nuj nqi yog qhov tseeb lub zog ua haujlwm .
