Lub derivative ntawm ib qho kev ua haujlwm yuav raug siv los txiav txim seb qhov haujlwm puas yog nce los yog txo ntawm ib qho ib ntus hauv nws lub npe. Yog tias f'(x) > 0 ntawm txhua lub ntsiab lus hauv ib qho lub sijhawm Kuv, ces cov nuj nqi yog hais tias yuav nce ntawm I. f'(x) <0 ntawm txhua qhov taw qhia hauv ib qho lub sijhawm Kuv, ces cov nuj nqi yog hais tias yuav txo ntawm kuv.
Tsis tas li ntawd, koj ua li cas thiaj nrhiav tau lub sijhawm nce?
Yuav nrhiav tau nce lub sijhawm ntawm ib tug muab function, ib tug yuav tsum txiav txim tus ib ntus qhov twg muaj nuj nqi muaj qhov zoo thawj derivative. Nrhiav cov no ib ntus , ua ntej nrhiav qhov tseem ceeb, los yog cov ntsiab lus ntawm cov thawj derivative ntawm lub luag haujlwm yog sib npaug rau xoom. Rau qhov muab ua haujlwm,.
Tsis tas li ntawd, kev coj cwj pwm kawg yog dab tsi? Cov kawg tus cwj pwm ntawm polynomial muaj nuj nqi yog qhov tus cwj pwm ntawm daim duab ntawm f(x) raws li x mus txog qhov zoo infinity lossis tsis zoo infinity. Lub degree thiab tus thawj coefficient ntawm ib tug polynomial muaj nuj nqi txiav txim lub kawg tus cwj pwm ntawm daim duab.
Tsis tas li lo lus nug yog, koj yuav nrhiav qhov tsawg kawg nkaus hauv zos li cas?
Yuav Ua Li Cas Nrhiav Hauv Zos Extrema nrog Thawj Qhov Kev Xeem Derivative
- Nrhiav thawj derivative ntawm f siv txoj cai fais fab.
- Teem lub derivative sib npaug rau xoom thiab daws rau x. x = 0, –2, lossis 2. Peb x-tus nqi no yog cov lej tseem ceeb ntawm f. Cov lej tseem ceeb ntxiv tuaj yeem tshwm sim yog tias thawj qhov sib piv tsis tau txhais ntawm qee qhov x-tus nqi, tab sis vim yog qhov sib txawv.
Yuav ua li cas koj pom concavity intervals?
Yuav Ua Li Cas Pom Qhov Nruab Nrab ntawm Concavity thiab Inflection Points
- Nrhiav qhov thib ob derivative ntawm f.
- Teem thib ob derivative sib npaug rau xoom thiab daws.
- Txiav txim siab seb qhov thib ob derivative tsis tau txhais rau ib qho x-tus nqi.
- Npaj cov lej no rau ntawm tus lej kab thiab sim cov cheeb tsam nrog qhov thib ob derivative.
