Kev daws literal equations feem ntau pab tau rau hauv lub neej tiag cov xwm txheej, piv txwv li peb tuaj yeem daws cov qauv rau kev ncua deb, d = rt, rau r los tsim ib qho kev sib npaug rau tus nqi. Peb yuav xav tau txhua txoj hauv kev los daws cov kauj ruam ntau kev sib npaug . Kev daws rau ib qho kev sib txawv hauv ib qho qauv.
Kuj paub tias, kev sib npaug yuav siv li cas hauv lub neej tiag?
lej kev sib npaug kuj yog siv nyob rau hauv kev tswj tsheb, aircraft, qhov chaw ua haujlwm thiab tshuaj thiab lwm yam. Yog li peb yuav tsum nco ntsoov tias txhua yam lej kev sib npaug qhov tshwm sim muaj peev xwm hloov tau ntiaj teb . Tias yog vim li cas tag nrho cov lej kev sib npaug tseem ceeb hauv peb lub neej.
Ib yam li ntawd, piv txwv li kev sib npaug li cas yog dab tsi? A literal equation yog ib tug uas muaj ob peb tsab ntawv los yog variables. Piv txwv suav nrog thaj tsam ntawm lub voj voog (sab laug(A=pi {r}^{2} ight))) thiab cov qauv rau kev ceev (sab laug(v=frac{D}{t} ight)). Kev daws literal equations tseem hu ua hloov cov ntsiab lus ntawm cov qauv.
Ib yam li ntawd, tib neeg nug, dab tsi yog qee qhov piv txwv ntawm lub neej tiag tiag ntawm cov haujlwm linear?
Teb Chaws Asmeskas: Puas muaj leej twg muab rau kuv piv txwv ntawm linear functions tiag tiag lub neej xwm txheej? Linear functions tshwm sim txhua lub sij hawm koj muaj a tus nqi hloov tsis tu ncua.
Cov piv txwv ntawm lub neej tiag tiag yog:
- Nrhiav tam sim no siv rau hnub 1, 2, 3…
- Koj nqa tsheb mus xauj.
- Koj tab tom tsav tsheb ntawm qhov ceev ntawm 60 km / h.
Vim li cas cov lus sib npaug tseem ceeb?
Literal equations tso cai siv los sawv cev rau tej yam xws li kev ncua deb, lub sij hawm, kev txaus siab, thiab txoj kab nqes raws li qhov sib txawv hauv ib qho kev sib npaug . Siv cov kev hloov pauv hloov cov lus yog lub sijhawm txuag tiag tiag!

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Puas yog txhua qhov sib npaug sib npaug sib npaug?
Thawj qhov sib npaug sib npaug yog qhov tseeb yog tias nws muaj kev txuag kom muaj nuj nqis. Piv txwv li, qhov sib npaug sib cais yeej ib txwm muaj tseeb, txij li lub ntsiab lus lawv yog ntawm daim ntawv: M(y) + N(t) = 0, yog li ϕ(t, y) = A(y) + B(t) yog a khaws cia kom muaj nuj nqis
Cov coefficients hauv kev sib npaug tshuaj sib npaug qhia koj li cas txog cov reactants thiab cov khoom?
Cov coefficients ntawm kev sib npaug chemicalequation qhia peb cov txheeb ze ntawm moles ntawm reactants thiab cov khoom. Hauv kev daws teeb meem stoichiometric, kev hloov pauv ntawm moles ntawm reactants rau moles ntawm cov khoom raug siv. Hauv kev suav loj, cov molar loj yog xav tau los hloov cov huab hwm coj mus rau moles
Yuav ua li cas cov khoom siv caj ces hauv txhua lub xov tooj tshiab tsim los ntawm kev faib tawm ntawm tes sib piv nrog cov khoom siv caj ces hauv lub xov tooj qub?
Mitosis tshwm sim nyob rau hauv ob lub nuclei uas zoo tib yam rau thawj nucleus. Yog li, ob lub hlwb tshiab tsim tom qab kev faib tawm ntawm tes muaj tib yam khoom siv caj ces. Thaum lub sij hawm mitosis, chromosomes condense los ntawm chromatin. Thaum saib nrog lub microscope, chromosomes pom nyob rau hauv lub nucleus
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
