Raws li x ze rau qhov zoo tsis kawg , ln x,vim mus rau infinity , nce qeeb dua ib qho zoo zog, xa (txawm tias lub zog feem ntau xws li a = 1/200). Raws li x -> 0+, - ln x mus rau infinity , tab sis maj mam ntau dua li lub zog tsis zoo, x-a (txawm yog ib feem).
Ib yam li ntawd, dab tsi yog lub ntuj log ntawm infinity?
Ntuj logarithm cov cai thiab cov khoom
| Txoj cai lub npe | Txoj cai |
|---|---|
| ln zoj | ln(0) yog undefined |
| ln ib | ln(1) = 0 |
| Nyob rau hauv infinity | lim ln(x) = ∞, x → ∞ |
| Euler tus kheej | ln(-1) = np |
Tsis tas li ntawd, puas yog LN Infinity xoom? ln ( 0 ) tsis muaj nqi! Lub logarithm ntawm xoom ( 0 ) ASPROACHES minus tsis kawg , tsis hais lub hauv paus. Txhawm rau kom nkag siab qhov no, daim duab teev n los ntawm ib qho zoo n (Kuv xav n = 100, yooj yim scaled) rau n = txhua tus lej zoo tsawg dua 1.
Ib yam li ntawd, tib neeg nug, koj puas tuaj yeem nqa lub cav ntuj ntawm infinity?
Cov lus teb yog ∞. Cov natural log muaj nuj nqi yog nruj me ntsis nce, yog li nws yog ib txwm loj hlob albeit maj mam. Qhov derivative yog y' = 1x ces nws yeej tsis 0 thiab ib txwm zoo. Yog li ntawd, n yuav tsum loj.
Puas yog lub log ntawm 0 infinity?
log 0 yog undefined. Nws tsis yog tus lej tiag tiag, vim tias koj tsis tuaj yeem tau txais xoom los ntawm kev nce ib yam dab tsi rau lub zog ntawm lwm yam. Koj tsis tuaj yeem ncav cuag xoom, koj tsuas tuaj yeem mus rau nws siv lub zog loj thiab tsis zoo. Qhov no yog vim muaj tus naj npawb tau tsa 0 sib 1.

Thaum x mus txog infinity Qhov txwv yog dab tsi?
Nyob rau hauv cov ntaub ntawv no, vim hais tias ob nqe lus yog tib yam degree, qhov txwv yog sib npaug zos rau 0 (thiab ib tug ceev glance ntawm daim duab ntawm y = sqrt(x-1) - sqrt(x) paub meej tias raws li x mus infinity, y mus kom ze 0)
Nws puas yuav ua rau pom qhov sib npaug ntawm kab sib npaug mus rau ib kab thiab los ntawm ib qho taw tes ntawm kab?
Qhov sib npaug ntawm ib kab uas yog parallel lossis perpendicular rau ib kab? Cov lus teb tau: Cov nqes hav ntawm cov kab sib npaug sib npaug. Hloov txoj kab nqes paub thiab cov kev sib koom ua ke ntawm ib qho taw tes ntawm lwm txoj kab rau hauv daim ntawv point-slope kom pom qhov sib npaug ntawm kab sib npaug
Dab tsi yog qhov txwv ntawm E x li x mus txog infinity?
Qhov kev txwv ntawm infinity ntawm ib tug polynomial uas nws cov coefficient yog qhov zoo yog infinity. Txij li thaum tus exponent x x mus txog ∞ ∞, qhov ntau ex e x mus txog ∞ ∞
Puas yog infinity kos npe rau tus lej?
Hauv kev sau ntawv, infinity tuaj yeem raug sau tseg los ntawm cov cim lej tshwj xeeb hu ua lub cim infinity (∞) tsim los ntawm John Wallis, tus kws lej Askiv uas muaj sia nyob thiab ua haujlwm hauv xyoo pua 17th. Lub cim infinity zoo li kab rov tav version ntawm tus lej 8 thiab nws sawv cev rau lub tswv yim ntawm kev nyob mus ib txhis, tsis muaj qhov kawg thiab tsis txwv
Lub zog rau kev thauj mus los ntawm qhov twg thiab vim li cas thiaj li xav tau lub zog rau kev thauj mus los?
Kev thauj mus los nquag yog txheej txheem uas yuav tsum tau txav cov molecules tawm tsam qhov concentration gradient. Cov txheej txheem yuav tsum muaj zog. Lub zog rau cov txheej txheem tau txais los ntawm kev rhuav tshem cov piam thaj siv oxygen hauv kev ua pa aerobic. ATP yog tsim thaum ua pa thiab tso tawm lub zog rau kev thauj mus los
