Marginal cov nqi yog qhov taw qhia ntawm qhov kev lag luam marginal nyob rau hauv kev ua haujlwm ntawm kev lag luam, qee qhov nqi ntxiv siv rau kev tsim khoom ntawm txhua chav ntawm cov khoom lag luam ntxiv. Ntxiv mus, rau txhua theem ntawm kev tsim khoom muaj qhov tshwj xeeb, muaj qhov sib txawv ntawm cov nqi no.
Cov Lus Qhia
Kauj ruam 1
Kev nce ntawm cov nqi nce mus nce los, uas cuam tshuam nrog kev tso tawm ntawm txhua qhov ntxiv ntawm cov khoom lag luam, uas yog, qhov sib piv ntawm qhov nce ntawm cov nqi mus rau qhov nce ntawm cov khoom lag luam uas tshwm sim los ntawm lawv qhia qhov loj me ntawm cov nqi sib txawv. Yog li, nws tuaj yeem txiav txim siab siv cov qauv hauv qab no: Tus nqi nce siab = nce tus nqi nce mus nce los / nce hauv ntau lawm.
Kauj ruam 2
Piv txwv, yog tias qhov nce hauv kev muag khoom tau nce txog 1000 units ntawm cov khoom lag luam, thiab lub tuam txhab cov nqi nce 8000 rubles, ces cov nqi pib yuav: 8000/1000 = 8 rubles - qhov no txhais tau tias txhua qhov ntxiv ntawm cov nqi khoom hauv tuam txhab ntxiv 8 rubles.
Kauj ruam 3
Nyeg, nrog rau kev ua kom muaj txiaj ntsig, nrog rau kev muag khoom, lub tuam txhab cov nqi tuaj yeem hloov: nrog kev ua kom qeeb, nrog kev ua kom nrawm lossis zoo ib yam.
Kauj ruam 4
Yog tias lub koomhaum cov nqi ntawm yuav cov khoom siv thiab cov khoom siv raw tsawg zuj zus vim cov khoom ntim ntau lawm, tom qab ntawv cov nqi tsawg dhau nrog kev poob qis.
Kauj ruam 5
Lub marginal nqi nce ntxiv raws li qhov ntim ntawm qhov nce ntxiv ntawm tus nrawm. Cov xwm txheej no tuaj yeem piav qhia los ntawm kev ua haujlwm ntawm txoj cai ntawm kev poob qis rov qab los yog nce tus nqi ntawm cov khoom siv raw, cov ntaub ntawv lossis lwm yam rau cov nqi tau muab cais ua cov hloov pauv.
Kauj Ruam 6
Tus yam ntxwv ntawm kev hloov pauv tsis txawv ntawm cov nqi yuav luag ib txwm muaj sib luag thiab sib luag rau cov nuj nqis uas tsis txawv txav siv rau ib ntu ntawm cov khoom.
Kauj Ruam 7
Mathematically, marginal nqi ua tshwj xeeb kev derivatives ntawm tus nqi muaj nuj nqi rau ib hom kev ua si.
Kauj ruam 8
Kev lag luam qis txheej txheem txhais tau hais tias yuav tsum muaj qhov ntau ntawm cov peev txheej ntxiv xav tau los tsim cov khoom lag luam ntau ntxiv. Qhov no, nyeg, ua rau muaj nuj nqi siab. Los sis rov ua dua.
Kauj Ruam 9
Cov nqi tsim khoom tsis tuaj yeem cuam tshuam txog theem ntawm cov nqi tsis tseem ceeb rau lub sijhawm qhia, lawv tsuas txiav txim siab los ntawm cov nqi sib txawv.
