Yog muaj ib tug Liapunov muaj nuj nqi Λ forc, ces c yog a ruaj khov taw tes . Yog Λ yog astrict Liapunov muaj nuj nqi rau c, ces c yog asymptotically ruaj khov taw tes.
Ua li no, qhov chaw ruaj khov yog dab tsi?
Ib qho ntxim nyiam tsau point hais tias yog ib ruaj khov taw tes Yog hais tias nws tseem yog Lyapunov ruaj khov . A tsau point hais tias yog ib tug nruab nrab ruaj khov fixedpoint Yog hais tias nws yog Lyapunov ruaj khov tab sis notattracting.
Kuj Paub, vim li cas cov ntsiab lus ruaj khov tseem ceeb? Tsau cov ntsiab lus muaj kev txaus siab rau lawv tus kheej tab sis lawv kuj muab ib txoj hauv kev los tsim kom muaj lub neej ntawm kev daws teeb meem rau kev sib npaug.
Ntxiv rau qhov no, lub ntsiab lus tseem ceeb hu ua dab tsi?
Ib tug parabola yog txheej ntawm cov ntsiab lus equidistant los ntawm kab, hu ua directrix, thiab a tsau point , hu ua qhov tsom. Ib tug parabola yog ib txheej ntawm cov ntsiab lus uas yog equidistant los ntawm ib tug muab kab, uas peb hu ua lub directrix, thiab muab tsau point tsis nyob ntawm kab, hu ua kev tsom xam. Cia ua ntej teeb tsa txoj kab no thiab qhov no taw tes.
Dab tsi yog fixed point format?
Hauv kev suav, a tsau - taw tes Numberrepresentation yog hom ntaub ntawv tiag tiag rau tus lej uas muaj a tsau tus lej tom qab (thiab qee zaum kuj ua ntej) theradix taw tes (tom qab tus lej taw tes '.' hauv English decimal notation).

Koj yuav ua li cas thiaj paub tias qhov sib npaug ua haujlwm lossis tsis yog?
Nws kuj yog ib qho yooj yim los txiav txim seb qhov sib npaug yog qhov ua haujlwm los ntawm kev daws rau y. Thaum koj muab ib qho kev sib npaug thiab tus nqi tshwj xeeb rau x, qhov yuav tsum tsuas yog ib qho sib txuas y-tus nqi rau qhov x-tus nqi.Txawm li cas los xij, y2 = x + 5 tsis yog qhov ua haujlwm; yog tias koj xav tias x = 4, ces y2 = 4 + 5 = 9
