Teb: Peb kev tsis sib xws tau dashed ciam teb . peb kev tsis sib xws muab dashed kab ciam teb.

Yog li ntawd, thaum kos duab ib qho kev tsis sib xws ntawm ib txoj kab dashed yog dab tsi?

Yog tias ciam teb kab yog dashed ces cov kev tsis sib xws tsis suav nrog qhov ntawd kab . Qhov ntawd txhais tau hais tias qhov sib npaug tsuas yog siv ob qho tib si ntawm thawj ob lub cim. Ntawm qhov tod tes, ib qho txuas ntxiv kab nrog tsis so txhais tau tias tus kev tsis sib xws suav nrog ciam teb kab.

Ib yam li ntawd, sab ntawm kab twg koj ntxoov ntxoo thaum kos duab tsis sib xws? Ua ntej, kos cov kab "sib npaug", tom qab ntawd ntxoov ntxoo hauv qhov tseeb. Muaj peb kauj ruam: Rov ua qhov sib npaug kom "y" nyob rau ntawm sab laug thiab txhua yam nyob rau hauv txoj cai . lossis hauv qab kab rau "tsawg dua" (y< lossis y≦).

Hais txog qhov no, dab tsi yog ib tug dashed kab nyob rau hauv graphing?

Daim duab Kev tsis sib xws. Yog qhov tsis sib xws, daim duab equation as a kab dotted . Yog tias qhov tsis sib xws yog ≦ lossis ≧, daim duab qhov sib npaug ua ib qho khoom kab . Qhov no kab faib lub xy- dav hlau mus rau ob thaj tsam: ib cheeb tsam uas txaus siab rau qhov tsis sib xws, thiab ib cheeb tsam uas tsis muaj.

Ib txoj kab dashed txhais li cas?

Thaum siv a dash kab los tsim ib tug ciam teb uas ploj lawm, nws tuaj yeem qhia qhov zais ntawm qhov khoom. Los ntawm cov rooj sib tham, technical thiab engineering illustrations siv cov khoom kab rau qhov pom thiab qhov dashed los yog kab dotted los qhia zais kab thiab ntug.
