Yuav ua li cas yog cov khoom ntawm cov lej lej lej lej lej lej Ib qho lej lej lossis lej lej yogcov lej xws li qhov sib txawv ntawm cov lus sib law liag . Piv txwv li, kab lus 5, 7, 9, 11, 13, 15,… yog ib qho kev ua lej lej nrog qhov sib txawv ntawm 2. https://en.wikipedia.org › wiki › Arithmetic_progression
Kev nce qib lej - Wikipedia
? Ua ntej peb saib cov ntaub ntawv tsis tseem ceeb ntawm ib ntu tas mus li a =a for all n. Peb tam sim ntawd pom tias xws li ib ntus yog bounded; Tsis tas li ntawd xwb, nws yog monotone, uas yog nws tsis txo qis thiab tsis nce.
Puas yog tag nrho cov sequences monotonic?
Peb xav tau cov hauv qab no. Ib ntus (a ) yogmonotonic nce yog tias a +1≥ a rau txhua tus n∈ N. Cov kab ke yog nruj me ntsis monotonic nce yog tias peb muaj > hauv qhov txhais. Monotonic txo cov sequences raug txhais zoo ib yam.
piv txwv monotonic sequence yog dab tsi?
Monotonicity: Cov kab ke sn tau hais kom nce ntxiv yog sn sn + 1 rau tag nrho n 1, i.e., s1 s2 s3 …. … Ib ntu tau hais tias yog monotone yog tias nws nce lossis txo qis. Piv txwv. Cov kab ke n2: 1, 4, 9, 16, 25, 36, 49, … yog nce.
Dab tsi txhais cov kab lus monotonic?
Monotone Sequences. Txhais: Peb hais tias ib ntus (xn) yognce yog xn ≤ xn + 1 rau tag nrho n thiab nruj me ntsis nce yog xn < xn + 1 rau tag nrho n. Ib yam li ntawd, peb txhais cov kev txo qis thiab nruj me ntsis txo cov kab ke. Cov kab ke uas nce lossis txo qis yog hu ua monotone.
Koj ua pov thawj li cas ib ntus yog monotonic?
an≥an+1 rau txhua tus n∈N. Yog {ib} nce lossis txo qis , ces nws hu ua monotone sequence.
Ua pov thawj tias txhua qhov sib txuas hauv qab no yog convergent thiab nrhiav nws txwv.
- a1=1 thiab +1=an+32 rau n≥1.
- a1=√6 and an+1=√an+6 for n≥1.
- an+1=13(2an+1a2n), n≥1, a1>0.
- an+1=12(an+ban), b>0.

Puas yog qhov kev sib cav sib cav sib ceg puas tau faib lub tebchaws byzantine?
Kev sib cav thiab kev sib cav hauv chav kawm tau muab tso rau pem hauv ntej, xws li lub cim ntawd tsim kev sib faib nom tswv thiab nyiaj txiag hauv Byzantine haiv neeg; tias feem ntau nws tau txais kev txhawb nqa los ntawm cov neeg sab hnub tuaj, cov neeg pluag, tsis yog Greek cov neeg ntawm lub teb chaws Ottoman uas yuav tsum tau cuam tshuam nrog Arab raids.
Puas yog kev sib ntaus sib tua ntawm kev sib ntaus sib tua?
Kev sib ntaus sib tua ntawm Hastings, uas Anglo-Saxon huab tais Harold II tau sim tiv thaiv nws lub tebchaws los ntawm kev tawm tsam ntawm William, duke ntawm Normandy (tom qab hu ua William tus Conqueror), tau tshwm sim rau 14 October 1066.
Puas yog lawv kho kev sib ntaus sib tua 2?
Sure, EA tsis tau kho qhov kev puas tsuaj ntawm Battlefront 2. … Tab sis tsis yog, lawv tau ntaus lub rooj tsav xwm kos duab thiab tso tawm cov kev txhim kho dawb rau cov neeg uas them rau Battlefront 2. Tsis tshua muaj peb puas tau tuaj hla cov neeg tsim khoom siv txhaj tshuaj thib ob ntawm qhov kev ua si phem los ua kom nws zoo dua.
Dab tsi yog polyadenylation teeb liab sib lawv liag?
Lub teeb liab polyadenylation - cov kab ke motif lees paub los ntawm RNA cleavage complex- sib txawv ntawm pab pawg ntawm eukaryotes. … Qhov chaw cleavage txuam nrog lub teeb liab polyadenylation tuaj yeem sib txawv txog li 50 nucleotides. Thaum lub RNA yog cleaved, polyadenylation pib, catalysed los ntawm polyadenylate polymerase.
Leej twg tau txais khoom plig nobel sib law liag?
Yog tias tau txais qhov khoom plig Nobel yog qhov kev lees paub siab tshaj plaws rau tus kws tshawb fawb, tau txais ob zaug los ntawm Swedish Academy of Sciences yog qhov tseeb tshwj xeeb uas, txog tam sim no, tsuas yog plaub tus neeg tuaj yeem khav:
