Kev tshem tawm tsis tu ncua yog taw tes rau ntawm daim duab uas tsis tau txhais lossis tsis haum rau qhov seem ntawm daim duab Muaj ob txoj hauv kev tshem tawm tsis tau tsim. Ib txoj hauv kev yog los ntawm kev txhais lub blip hauv txoj haujlwm thiab lwm txoj hauv kev yog los ntawm kev ua haujlwm uas muaj qhov sib xws hauv tus lej thiab tus lej.
Yuav ua li cas koj thiaj paub yog tias nws yog kev tshem tawm tsis tau?
Yog tias cov haujlwm tseem ceeb thiab lub sijhawm hauv qab tshem tawm, qhov tsis sib xws ntawm x-tus nqi uas tus denominator yog xoom yog tshem tau, yog li daim duab muaj qhov nyob hauv nws. Tom qab tshem tawm, nws tawm koj nrog x – 7. Yog li ntawd x + 3=0 (los yog x=–3) yog ib qho kev tshem tawm tsis tu ncua - daim duab muaj lub qhov, zoo li koj pom hauv daim duab a.
3 yam kev tsis sib haum yog dab tsi?
Muaj peb hom kev tsis sib xws: Tshem tau, dhia thiab tsis kawg.
Puas yog kev tshem tawm tsis tu ncua yog ntsug asymptote?
Qhov txawv ntawm "kev tshem tawm tsis tu ncua" thiab "ntug asymptote" yog tias peb muaj R. tsis txuas ntxiv yog tias lo lus uas ua rau tus lej ntawm qhov muaj nuj nqis sib npaug ntawm xoom rau x=a rho tawm raws li qhov kev xav tias x tsis sib npaug rau a. Tsis tas li ntawd, yog tias peb tsis tuaj yeem "tso tseg" nws tawm, nws yog qhov ntsug asymptote.
Kev tshem tawm tsis tu ncua txhais li cas?
Point/removable discontinuity is thaum muaj ob sab kev txwv, tab sis tsis sib npaug rau qhov muaj nuj nqis. Dhia tsis tu ncua yog thaum qhov txwv ob sab tsis muaj vim tias qhov txwv ib sab tsis sib npaug.
