Yog tias ob equations piav kab sib npaug , thiab li ntawd kab uas tsis sib tshuam, lub system yog ywj siab thiab tsis sib xws . Yog tias ob equations piav tib yam kab , thiab li ntawd kab uas cuam tshuam tus naj npawb tsis kawg ntawm lub sijhawm, qhov system yog nyob ntawm thiab zoo ib yam.

Tom qab ntawd, ib tug kuj yuav nug, ua li cas koj thiaj paub yog tias ob qhov sib npaug sib npaug lossis tsis sib xws?

Yog tias ib qho kev sib raug zoo muaj ib qho kev daws teeb meem, nws yog ywj siab

  1. Yog hais tias ib tug zoo ib yam system muaj ib tug infinite cov kev daws, nws yog nyob ntawm seb. Thaum koj kos cov kab zauv, ob qho tib si sib npaug sawv cev tib kab.
  2. Yog tias qhov system tsis muaj kev daws teeb meem, nws tau hais tias tsis sib haum.

Puas yog qhov kev sib npaug sib npaug sib npaug thiab sib npaug lossis tsis sib xws? A system ntawm equations yog zoo ib yam yog tias nws muaj tsawg kawg yog ib qho kev daws teeb meem. Cov qhov system yog zoo ib yam thiab coincident yog hais tias nws muaj ib tug daws tab sis tus naj npawb ntawm cov kev daws yog infinite. Cov qhov system yog tsis sib xws yog tsis muaj kev daws teeb meem. Thaum peb tuaj txog ntawm hom lus teb no, qhov sib npaug txaus siab txawm tias tus nqi X yuav siv li cas.

Hauv qhov no, txhais tau li cas los ntawm qhov tsis sib xws thiab tsis sib xws?

Teb: Zoo ib yam = kab sib tshuam ntawm qhov taw tes uas sawv cev rau qhov kev daws teeb meem tshwj xeeb ntawm cov kab ke ntawm kab sib npaug hauv ob qhov sib txawv. Algebraically, yog tias, cov kab zauv sib npaug 'pab yog zoo ib yam . Tsis sib haum = kab uas yog parralel tsis sib xws.

Nws txhais li cas kom sib haum?

Ib tug yog zoo ib yam ib txwm coj tus cwj pwm zoo ib yam, muaj tus cwj pwm tib yam rau tib neeg lossis txhua yam, lossis ua tiav tib theem ntawm kev vam meej hauv ib yam dab tsi. Yog ib qhov tseeb los yog lub tswv yim zoo ib yam nrog lwm tus, lawv ua tsis sib cav sib ceg.
