Qhov sib npaug rau koj cov lus nug yog: ln ( tsis kawg ) = x thiab koj xav paub x. Ib zaug ntxiv, qhov no tsis raug cai vim e^x yeej tsis sib npaug tsis kawg . ln ( tsis kawg ) = x thiab koj xav paub x.
Tsuas yog li ntawd, dab tsi yog lub ntuj cav 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, 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.
Tsis tas li ntawd, Ln ntawm infinity tshaj infinity yog dab tsi?
Qhov txwv ntawm lub ntuj logarithm ntawm x thaum x ze tsis kawg yog tsis kawg : lim ln (x) = ∞
Puas yog LN Infinity zero?
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.

Dab tsi yog infinity ntawm digital ohmmeter?
Nyob rau hauv ib tug multimeter, infinity qhia ib tug qhib Circuit Court. Ntawm ib qho analog multimeter, infinity qhia tau hais tias yog ib rab koob tsis muaj zog uas yuav tsis txav mus deb ntawm sab laug ntawm cov zaub. Ntawm lub multimeter digital, infinity nyeem "0. Ntawm lub multimeter, "zero" txhais tau hais tias lub kaw lus kaw tau raug kuaj pom
Lub npe rau pawg Quadrilaterals yog dab tsi rau cov plaub lub kaum sab xis yog 90?
Nws yog 'niam txiv' ntawm qee qhov quadrilaterals, uas tau txais los ntawm kev ntxiv kev txwv ntawm ntau yam: Ib lub duab plaub yog ib qho parallelogram tab sis nrog tag nrho plaub lub kaum sab hauv kho ntawm 90 ° A rhombus yog ib qho parallelogram tab sis nrog tag nrho plaub sab sib npaug ntawm qhov ntev
Dab tsi yog cov reagents xav tau rau PCR thiab dab tsi yog qhov ua haujlwm ntawm txhua tus?
Muaj tsib yam tshuaj reagents, lossis cov khoom xyaw, siv hauv PCR: qauv DNA, PCR primers, nucleotides, PCR tsis thiab Taq polymerase. Primers feem ntau yog siv nyob rau hauv khub, thiab DNA ntawm ob lub primers yog amplified thaum lub sij hawm PCR cov tshuaj tiv thaiv
Dab tsi yog qhov txawv ntawm Marine West Coast huab cua thiab dab tsi yog lub luag haujlwm rau cov yam ntxwv ntawd?
Cov ntsiab lus ntawm Marine West Coast Qhov kev nyab xeeb ntawm cov yam ntxwv tseem ceeb yog lub caij ntuj sov me me thiab lub caij ntuj no thiab cov nag lossis daus txhua xyoo. Qhov ecosystem no muaj kev cuam tshuam loj heev los ntawm nws qhov ze rau ntawm ntug dej hiav txwv thiab roob. Nws yog qee zaum hu ua huab cua sab hnub poob ntug dej hiav txwv lossis dej hiav txwv huab cua
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
