Muaj nuj nqi . Tej zaum koj feem ntau paub txog cov cim sawv cev ntawm muaj nuj nqi , xws li equation, y = f(x). Muaj nuj nqi tuaj yeem sawv cev los ntawm cov rooj, cim , los yog graphs.
Hauv qhov no, kev sawv cev ua haujlwm yog dab tsi?
Ib txoj cai ua haujlwm tuaj yeem ua tau sawv cev nyob rau hauv ntau txoj kev. Piv txwv li, peb tuaj yeem qhia yuav ua li cas los ntawm ib qho muaj nuj nqi input rau nws cov zis siv ib tug qauv, ib daim duab, los yog ib lub rooj ntawm qhov tseem ceeb. Feem ntau, peb daws teeb meem nrog algebraic, graphical, thiab lej sawv cev ntawm kev ua haujlwm nrog txoj kev sib txawv heev.
Tsis tas li ntawd, lub cim ua haujlwm yog dab tsi? Functional notation Raws li thawj zaug siv los ntawm Leonhard Euler nyob rau hauv 1734, functions yog denoted los ntawm ib lub cim uas muaj feem ntau ntawm ib tsab ntawv nyob rau hauv italic font, feem ntau yog cov tsiaj ntawv qis. f ,g, hnu.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog lub cim sawv cev hauv lej?
lej notation yog ib qhov system ntawm cov cim sawv cev ntawm lej khoom thiab tswv yim. lej notations yog siv nyob rau hauv lej , lub cev sciences, engineering, thiab economics.
Dab tsi yog txoj hauv kev sib txawv los sawv cev ua haujlwm?
Ntsiab Lus
- Ib txoj haujlwm tuaj yeem sawv cev hais lus. Piv txwv li, lub voj voog ntawm ib lub square yog plaub npaug ntawm nws sab.
- Ib txoj haujlwm tuaj yeem sawv cev algebraically. Piv txwv li, 3x + 6 3 x + 6.
- Ib txoj haujlwm tuaj yeem sawv cev rau tus lej.
- Ib tug muaj nuj nqi yuav sawv cev graphically.

Dab tsi yog qhov txawv ntawm qhov kev txwv tsis kawg thiab kev txwv ntawm infinity?
Daim ntawv ceeb toom yuav ua li cas thaum peb tab tom cuam tshuam nrog qhov kev txwv tsis kawg, nws yog qhov ntsug asymptote. Kev txwv ntawm infinity yog asymptotes ib yam nkaus, txawm li cas los xij, cov no yog kab rov tav asymptotes peb tab tom cuam tshuam nrog lub sijhawm no. Cov kev txwv ntawm infinity muaj teeb meem qhov twg "txwv li x mus txog infinity lossis tsis zoo infinity" yog nyob rau hauv cov cim
Dab tsi yog qee qhov piv txwv ntawm qhov sib npaug ntawm kev txav mus los?
Kev sib npaug ntawm Kev Sib Tw Rau Cov Khaub Ncaws Kev Ua Si nrawm nrawm, tsav tsheb, thiab txawm tias tsuas yog taug kev yog txhua txhua hnub piv txwv ntawm kev txav. Kev sib raug zoo ntawm cov khoom no yog hu ua qhov sib npaug ntawm kev txav
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
Dab tsi yog qee qhov piv txwv ntawm kev cuam tshuam tsis zoo ntawm tib neeg ib puag ncig kev cuam tshuam?
