The point x=a txiav txim siab qhov taw tes rau kev ua haujlwm f yog tias f txuas ntxiv ntawm x=a, thiab qhov thib ob derivative f '' yog qhov tsis zoo (-) rau xa, los yog f'' yog zoo (+) rau xa. 8.
Yuav ua li cas koj pom qhov taw tes ntawm inflection?
Ib qho taw qhia ntawm kev ua txhaum yog pom qhov twg daim duab (lossis duab) ntawm kev ua haujlwm hloov pauv concavityTxhawm rau nrhiav qhov algebraically, peb xav nrhiav qhov twg qhov thib ob derivative ntawm cov haujlwm hloov pauv kos npe, los ntawm qhov tsis zoo mus rau qhov zoo, los yog vice-versa. Yog li, peb pom qhov thib ob derivative ntawm lub luag haujlwm muab.
YPuas X puas muaj qhov cuam tshuam?
Yog li peb tuaj yeem pom tias txoj haujlwm muaj qhov sib txawv ntawm ob sab ntawm x=0 thiab qhov taw qhia inflection yog ntawm x=0. Nco ntsoov qhov inflection point tsis yog qhov uas muaj nuj nqi hla lub x-axis tab sis yog qhov twg qhov concavity hloov pauv.
Puas yog qhov taw tes X lossis Y?
txhawm rau nrhiav x-kev sib koom tes ntawm qhov taw tes ntawm kev ua txhaum, peb teeb tsa qhov thib ob derivative ntawm qhov ua haujlwm sib npaug rau xoom. \displaystyle x=\frac{6}{12}=\frac{1}{2}. Txhawm rau nrhiav y-coordinate ntawm lub ntsiab lus, peb ntsaws x-coordinate rov qab mus rau qhov qub ua haujlwm.
Yuav ua li cas ntawm qhov taw tes ntawm inflection?
Cov ntsiab lus nkag siab yog cov ntsiab lus uas lub luag haujlwm hloov pauv qhov sib txawv, piv txwv li los ntawm "concave up" mus rau "concave down" lossis vice versa. … Zoo ib yam li cov ntsiab lus tseem ceeb hauv thawj qhov derivative, cov ntsiab lus inflection yuav tshwm sim thaum qhov thib ob derivative yog xoom lossis tsis tau txhais.

Qhov taw qhia ntawm tes teeb liab los ntawm lub teeb daj yog?
Lub ntsiab teeb liab daj teeb nrog sab tes xis taw qhia qhov taw qhia teeb. Indicates - RIGHT HAND DIVERSION. (1) Lub Nres Pib ntsais koj teeb uas tswj kev txav ntawm cov tsheb ciav hlau mus txog qhov chaw nres tsheb yog peb yam, xws li - Sab Nraud, Tsev thiab Routing signals .
Ntawm qhov taw tes saturation mu ntawm cov khoom yog?
Thaum TU yog siab tshaj plaws hu ua saturation point MU yog zero Units ntawm cov khoom yog 1. Thaum Marginal Utility yog xoom, Total Utility yog siab tshaj . MU yog dab tsi ntawm taw tes ntawm saturation? Saturation point yog taw tes uas MU yog xoom thiab TU yog qhov siab tshaj plaws, txawm li cas los xij, kev noj tom qab saturation taw tes ua rau poob hauv TU, thaum MU ua tsis zoo .
Puas taw tes taw qhia ib txwm muaj?
Lub npe pointer los ntawm dog lub siab xav rau taw tes, los ntawm kev tso tseg thiab tsom nws lub muzzle ntawm kev ua si. Qhov no qhia rau tus neeg yos hav zoov qhov chaw ntawm lawv cov chaw txua txiag zeb thiab tso cai rau lawv txav mus rau hauv rab phom ntau.
Qhov taw tes stagnation nyob qhov twg?
Nyob rau hauv dej dynamics, ib tug stagnation point yog ib tug taw tes nyob rau hauv ib tug khiav teb uas lub zos tshaj tawm ntawm cov dej yog xoom . Yuav ua li cas yog txoj hauj lwm ntawm stagnation? Kev piav qhia: Lub ntsiab lus stagnation txav mus rau sab qis ntawm lub tog raj kheej, zoo ib yam li cov theoretical ntws.
Leej twg kuaj pom qhov taw tes ntawm qhov siab tshaj plaws ntawm photosynthesis?
Teb: Ib tus kws tshawb fawb los ntawm lub npe Emerson ua pov thawj tias qhov siab tshaj plaws ntawm photosynthesis tshwm sim ntawm liab thiab xiav rays. Kev piav qhia: Qhov kev sim no paub los ntawm lub npe ntawm Emerson Enhancement Experiment.
