Tam sim no peb tuaj yeem daws qhov sib npaug Quadratic hauv 5 kauj ruam:
- Kauj Ruam 1 Faib tag nrho cov ntsiab lus los ntawm a (the coefficient ntawm x2).
- Kauj Ruam 2 Txav tus lej sij hawm (c/a) mus rau sab xis ntawm kab zauv.
- Kauj ruam 3 Ua kom tiav lub square nyob rau sab laug ntawm qhov sib npaug thiab sib npaug qhov no los ntawm kev ntxiv tus nqi qub rau sab xis ntawm qhov sib npaug.
Hauv qhov no, coefficients yog dab tsi?
Hauv lej, a coefficient yog ib qho kev sib txuam hauv qee lub sij hawm ntawm polynomial, series, lossis ib qho kev qhia; nws feem ntau yog tus lej, tab sis tej zaum yuav yog ib qho kev qhia. Piv txwv li, yog tias y raug suav tias yog ib qho parameter hauv cov lus hais saum toj no, qhov coefficient ntawm x yog −3y, thiab qhov tsis tu ncua coefficient yog 1.5 + y.
Qhov thib ob, thaum twg koj tuaj yeem ua tsis tiav lub xwmfab? Los ntawm txoj kev, tshwj tsis yog koj 'tau hais tias koj yuav tsum siv ua kom tiav lub square , koj yuav tej zaum yeej tsis siv txoj kev no hauv kev xyaum tiag tiag thaum daws qhov sib npaug ntawm plaub fab. Ib txhia lwm txoj kev (xws li factoring) yuav ua kom pom tseeb thiab nrawm dua, lossis lwm yam Quadratic Formula (xyuas tom ntej) yuav siv tau yooj yim dua.
Yog li ntawd, dab tsi tas li yuav tsum tau ntxiv kom tiav lub square?
Cov tas li uas yuav tsum tau ntxiv thiab rho tawm yog (B) 1/64. yog siv los daws qhov quadratic equation los ntawm ua kom tiav square.
Thaum twg kuv yuav tsum ua kom tiav lub square?
Tom ntej no, yog hais tias tus coefficient ntawm lub squared lub sij hawm yog 1 thiab lub coefficient ntawm lub linear (middle) lub sij hawm yog txawm, ua kom tiav lub square yog ib txoj kev zoo rau siv. Thaum kawg, tus qauv quadratic yuav ua haujlwm ntawm txhua qhov kev sib npaug plaub npaug.

Koj yuav daws tau qhov system ntawm peb qhov sib npaug li cas los ntawm kev tshem tawm?
Xaiv ib qho sib txawv ntawm ob qhov sib npaug, hais qhov sib npaug (2) thiab (3), thiab tshem tawm qhov sib txawv. Kev daws qhov system tsim los ntawm kev sib npaug (4) thiab (5). Tam sim no, hloov z = 3 rau hauv kab zauv (4) kom pom y. Siv cov lus teb los ntawm Kauj Ruam 4 thiab hloov mus rau hauv ib qho kev sib npaug uas muaj qhov sib txawv ntxiv
Qhov twg yog acidic ntau dua ib qho kev daws ntawm pH 2 lossis kev daws ntawm pH 6?
Kev piav qhia: pH yog qhov ntsuas ntawm acidity lossis alkalinity ntawm cov tshuaj. concentration siab dua yog acidity. Yog li ib qho kev daws ntawm pH = 2 yog acidic ntau dua li ntawm pH = 6 los ntawm qhov zoo ntawm 10000
Koj yuav daws tau qhov teeb meem linear programming li cas los ntawm txoj kev ntawm cov ces kaum?
METHOD OF CONNERS Khiav cov teeb tsa ua tau (tej thaj tsam), S. Nrhiav qhov EXACT coordinates ntawm tag nrho cov vertices (kaum cov ntsiab lus) ntawm S. Ntsuas lub hom phiaj muaj nuj nqi, P, ntawm txhua vertex Qhov siab tshaj plaws (yog tias muaj) yog qhov loj tshaj ntawm tus nqi ntawm P ntawm vertex. Qhov tsawg kawg nkaus yog qhov tsawg tshaj plaws tus nqi ntawm P ntawm vertex
Koj yuav daws qhov sib npaug li cas los ntawm kev cais qhov sib txawv?
Cov txheej txheem yooj yim los cais qhov sib txawv yog "ua ib yam dab tsi rau ob tog" ntawm qhov sib npaug, xws li ntxiv, rho tawm, sib npaug, lossis faib ob sab ntawm qhov sib npaug los ntawm tib tus lej. Los ntawm kev rov ua cov txheej txheem no, peb tuaj yeem tau txais qhov sib txawv ntawm ib sab ntawm qhov sib npaug
Yuav ua li cas koj daws cov kev txwv nrog square cag?
VIDEO Ces, tus nqi ntawm 1 infinity yog dab tsi? Qhov tseem ceeb, 1 divoded los ntawm tus lej loj heev tau ze rau xoom, yog li… 1 faib los ntawm tsis kawg , yog tias koj tuaj yeem ncav cuag tsis kawg , yog 0. Ib sab saum toj no, koj yuav suav cov kev txwv li cas?
