Ua li no, koj yuav daws qhov teeb meem li cas?
Rau daws ib qho kev sib npaug txhais tau tias nrhiav txhua qhov tseem ceeb uas ua rau cov lus muaj tseeb. Rau daws ib equation duab , kos daim duab rau txhua sab, cov tswv cuab, ntawm qhov sib npaug thiab pom qhov twg cov nkhaus hla, sib npaug. Qhov x qhov tseem ceeb ntawm cov ntsiab lus no, yog cov kev daws teeb meem rau qhov sib npaug.
Tsis tas li ntawd, koj yuav daws tau li cas rau thaj tsam uas ua tau? Cov thaj tsam ua tau yog cov cheeb tsam ntawm daim duab uas muaj tag nrho cov ntsiab lus uas txaus siab rau txhua qhov kev tsis sib xws hauv ib qho system. Rau graph thaj tsam ua tau , thawj daim duab txhua qhov tsis sib xws hauv qhov system. Tom qab ntawd nrhiav thaj chaw uas tag nrho cov duab sib tshooj. Qhov ntawd yog thaj tsam ua tau.
Kuj paub, koj pom thaj chaw ua tau li cas hauv txoj kev graphical?
Graphical Method
- Kauj Ruam 1: Tsim cov LP (Linear programming) teeb meem.
- Kauj Ruam 2: Tsim ib daim duab thiab npaj cov kab txwv.
- Kauj Ruam 3: Txiav txim siab qhov siv tau ntawm txhua txoj kab txwv.
- Kauj Ruam 4: Txheeb xyuas thaj tsam kev daws teeb meem ua tau.
- Kauj Ruam 5: Teeb lub hom phiaj ua haujlwm ntawm daim duab.
- Kauj ruam 6: Nrhiav qhov zoo tshaj plaws point.
LPP teeb meem yog dab tsi?
Lus Txhais: Ib qho programming linear teeb meem muaj ib tug linear muaj nuj nqi kom maximized los yog minimized raug rau tej yam kev txwv nyob rau hauv daim ntawv ntawm linear equations los yog inequalities.

VIDEO Ib yam li ntawd, 4 kauj ruam los daws qhov sib npaug yog dab tsi? A 4-Step Guide to Solving Equations (Part 2) Kauj Ruam 1: Simplify txhua sab ntawm qhov sib npaug. Raws li peb tau kawm dhau los, thawj kauj ruam ntawm kev daws qhov sib npaug yog ua kom qhov sib npaug yooj yim li sai tau.
Koj daws teeb meem kinematic hauv physics li cas?
1-Dimensional daws teeb meem Cov kauj ruam Sau txhua qhov ntau qhov teeb meem muab rau koj (qhov pib thiab qhov kawg, qhov pib thiab qhov kawg tshaj tawm, nrawm, sijhawm, thiab lwm yam) Sau rau qhov ntau npaum li cas koj tab tom nrhiav. Nrhiav qhov sib npaug kinematic (lossis qee zaum ob qhov sib npaug) los txheeb xyuas cov khoom no. daws cov algebra
Koj yuav daws li cas rau t hauv PV nRT?
Rewrite the equation as nRt = PV n R t = P V. Faib txhua lo lus los ntawm nR thiab ua kom yooj yim. Faib txhua lub sij hawm hauv nRt = PV n R t = P V los ntawm nR n R
Yuav ua li cas koj daws cov hauv paus plaub hau nrog lub hwj chim?
VIDEO Ib yam li ntawd, puas exponents tshem tawm cov hauv paus square? Qhov ntawd txhais tau tias yog tias koj muaj qhov sib npaug nrog cov hauv paus plaub hau hauv nws, koj tuaj yeem siv qhov "squaring", lossis exponents , tshem tawm cov hauv paus plaub hau .
Koj yuav daws tau qhov system hauv algebra li cas?
Nov yog yuav ua li cas nws mus: Kauj Ruam 1: daws ib qho kev sib npaug rau ib qho ntawm qhov sib txawv. Kauj Ruam 2: Hloov qhov sib npaug mus rau lwm qhov sib npaug, thiab daws rau x. Kauj Ruam 3: Hloov x = 4 x = 4 x = 4 rau hauv ib qho ntawm qhov sib npaug qub, thiab daws rau y
