Peb tuaj yeem siv peb qhov ua haujlwm los kwv yees tus nqi ntawm qhov sib txawv ntawm qhov sib txawv rau qhov txawv txav uas nyob sab nraud ntawm peb cov ntaub ntawv. Nyob rau hauv cov ntaub ntawv no, peb tab tom ua extrapolation. Piv txwv li ua ntej cov ntaub ntawv nrog x nruab nrab ntawm 0 thiab 10 yog siv los tsim ib kab regression y=2x + 5.
Vim li cas peb thiaj li siv cov ntawv ntxiv?
Extrapolation yog tus txheej txheem ntawm kev nrhiav tus nqi sab nraum cov ntaub ntawv. Nws tuaj yeem hais tau tias nws pab kwv yees yav tom ntej! … Cov cuab yeej no tsis yog siv tau rau hauv kev txheeb cais nkaus xwb tab sis kuj tseem siv tau rau hauv kev tshawb fawb, kev lag luam, thiab txhua lub sijhawm muaj qhov xav tau los kwv yees tus nqi yav tom ntej tshaj qhov peb tau ntsuas.
Peb tuaj yeem siv qhov twg ntxiv?
Extrapolation yog siv nyob rau hauv ntau qhov kev tshawb fawb, zoo li hauv chemistry thiab engineering qhov twg feem ntau tsim nyog ntxiv. Piv txwv li, yog tias koj paub qhov voltages tam sim no ntawm ib qho system, koj tuaj yeem nthuav tawm cov ntaub ntawv los kwv yees seb lub kaw lus yuav teb li cas rau qhov siab dua.
Thaum twg peb tuaj yeem ntxiv cov ntaub ntawv?
10.7.
Extrapolation tshaj qhov cuam tshuam yog thaum tus nqi ntawm Y raug kwv yees dhau qhov ntau ntawm X data. Yog tias cov ntaub ntawv tsis tau saib xyuas (cov ntaub ntawv sab nraud ntawm qhov ntau ntawm X cov ntaub ntawv) tsis yog linear ces qhov kev kwv yees ntawm Y tuaj yeem cuam tshuam sab nraud ntawm kev ntseeg siab ntawm qhov kwv yees Y tus nqi.
Vim li cas peb thiaj siv extrapolation thiab interpolation?
Interpolation yog siv los kwv yeesQhov tseem ceeb uas muaj nyob rau hauv cov ntaub ntawv teev, thiab extrapolation yog siv los kwv yees qhov tseem ceeb uas poob sab nraum cov ntaub ntawv teev thiab siv paub qhov tseem ceeb los kwv yees tus nqi tsis paub. Feem ntau, interpolation yog txhim khu kev qha ntau tshaj extrapolation, tab sis ob hom kev twv yuav muaj txiaj ntsig rau ntau lub hom phiaj.

Peb siv qhov twg los ntsuas kev siv tau?
Kev ntsuas kev siv tau ua ntej ib qho kev txiav txim siab tsim qauvtau ua pab peb txheeb xyuas cov neeg siv qhov mob tseem ceeb tshaj plaws. Los ntawm kev soj ntsuam seb cov neeg siv coj li cas, peb tuaj yeem nthuav tawm cov kev xav tau latent uas tib neeg tsis hais thaum sib tham lossis kev soj ntsuam.
Thaum twg peb siv imbroglio?
Ib qho cuam tshuam thiab tsis meej pem; lub xeev tsis meej pem thiab teeb meem. (archaic) Ib tug tsis meej pem heap; ib tangle. (tsis tshua muaj) Ib tug tsis meej pem heap. Kev nkag siab tsis meej lossis tsis pom zoo. Kuv siv lo lus imbroglio li cas?
Thaum twg siv i.e. thiab thaum twg siv xws li?
I.e. yog ib qho luv luv rau kab lus id est, uas txhais tau tias "uas yog." I.e. yog siv los rov hais dua ib yam dab tsi uas tau hais yav dhau los txhawm rau kom meej nws lub ntsiab lus. E.g. luv luv rau exempli gratia, uas txhais tau tias "
Peb puas yuav cia siab tias peb yuav tau txais kev txhawb nqa thib peb?
Teb: Ntau lab tus neeg Asmeskas twb tau txais lawv qhov kev ntsuas thib peb. Thiab IRS yuav xa tawm ntau dua ob peb lub lis piam tom ntej. Yog li, yog tias koj tseem tsis tau txais koj cov nyiaj them poob haujlwm (piv txwv tias koj tsim nyog tau txais kev them nyiaj), nws yuav tsum tuaj sai sai.
Thaum twg peb xav txog daim duab peb sab ua equiangular?
Ib daim duab peb sab uas nws tag nrho peb sab thiab sab hauv cov ces kaum sib npaug yog hu ua daim duab peb sab equiangular. Rau ib daim duab peb sab kom sib npaug, qhov ntsuas ntawm tag nrho nws peb lub kaum sab hauv yuav tsum sib npaug li 60 degrees.
