lej . Convergence, nyob rau hauv lej , khoom (tshwj xeeb los ntawm tej yam infinite series thiab functions) ntawm mus txog ib tug txwv ntau thiab ntau ze ze li ib qho kev sib cav (kuj txawv) ntawm cov nuj nqi nce los yog txo los yog raws li tus naj npawb ntawm cov nqe lus ntawm lub series nce.

Tib neeg kuj nug, dab tsi yog convergent thiab divergent hauv lej?

Divergent thiab Convergent . Convergent sequence yog thaum dhau los ntawm qee cov ntsiab lus koj tau ua tiav lub sijhawm kawg thiab tas li raws li n mus txog infinity. Divergent sequence yog hais tias nyob rau hauv uas cov ntsiab lus yeej tsis ua tas mus li lawv tseem nce los yog txo thiab lawv mus rau infinity los yog -infinity li n mus infinity.

Tsis tas li ntawd, qhov piv txwv ntawm kev sib koom ua ke yog dab tsi? Lub ntsiab txhais ntawm kev sib koom ua ke hais txog ob lossis ntau yam uas tuaj ua ke, koom ua ke lossis hloov mus ua ib qho. Ib piv txwv ntawm convergence yog thaum cov neeg coob coob tsiv mus ua ib pab pawg.

Kuj nug, dab tsi yog diverge hauv lej?

Hauv lej , a sib txawv series yog ib qho infinite series uas tsis yog convergent, txhais tau hais tias infinite sequence ntawm ib feem ntawm cov series tsis muaj ib tug finite txwv. Yog hais tias ib tug series converges, tus kheej cov nqe lus ntawm koob yuav tsum mus zero.
