Puas yog Parabolically ib lo lus?
Ntawm lossis muaj daim ntawv parabola lossis paraboloid.
Tus paraboloid zoo li cas?
Qhov no yog tej zaum qhov yooj yim tshaj plaws ntawm txhua qhov chaw quadric, thiab feem ntau nws yog thawj qhov pom hauv chav kawm. Nws muaj qhov txawv "lub qhov ntswg-cone" tsos Qhov saum npoo no hu ua elliptic paraboloid vim tias cov kab hla ntsug yog tag nrho cov parabolas, thaum kab rov tav hla ntu yog ellipses.
Vim li cas nws thiaj hu ua hyperbolic paraboloid?
Hyperbolic paraboloids feem ntau hu ua "neeb," rau qhov laj thawj pom tseeb. Lawv lub npe stems los ntawm qhov tseeb hais tias lawv ntsug hla ntu yog parabolas, thaum kab rov tav hla ntu yog hyperbolas.
