Ib kab los ntawm ib sab kom txhua sab yog daim iav. Thaum cov duab yog folded nyob rau hauv ib nrab raws li axis ntawm symmetry, ces ob halves match up.
Koj txhais li cas los ntawm axis ntawm symmetry?
Lub axis ntawm symmetry ntawm parabola yog kab ntsug uas faib cov parabola rau hauv ob qhov sib xyaw ua ke. Lub axis ntawm symmetry ib txwm dhau los ntawm vertex ntawm parabola.
Dab tsi yog qhov piv txwv ntawm symmetry?
Ob sab ntawm daim duab ntawm ob sab ntawm lub axis ntawm symmetry zoo li daim iav duab ntawm ib leeg. Piv txwv li: Qhov no yog daim duab ntawm parabola y=x2 – 4x + 2 ua ke nrog nws cov axis ntawm symmetry x=2. Lub axis ntawm symmetry yog kab liab ntsug.
Muaj pes tsawg hom axis ntawm symmetry muaj?
Ib kab uas faib lossis faib ib qho khoom rau hauv ob qhov sib npaug, ob qho tib si ntawm cov duab iav ntawm ib leeg yog hu ua axis ntawm symmetry. Cov kab no ntawm axis faib cov khoom yuav yog ib qho ntawm peb hom uas yog: kab rov tav (x-axis), ntsug (y-axis), lossis inclined axis.
Vim li cas lub square thiaj muaj 4 kab sib luag?
Rau lub xwmfab, nws tuaj yeem folded hauv ib nrab ntawm kab pheeb ces kaum, kab rov tav ntu uas txiav cov xwmfab hauv ib nrab, lossis ntu ntsug uas txiav cov square hauv ib nrab. Yog li lub square muaj plaub kab ntawm symmetry.
Pom zoo:
Dab tsi yog ob sab symmetry tso cai kom txhais tau?
: symmetry nyob rau hauv uas zoo sib xws anatomical qhov chaw yog teem nyob rau hauv opposite sab ntawm ib tug nruab nrab axis kom tsuas yog ib lub dav hlau thiaj li faib tus neeg mus rau hauv ib qho tseem ceeb halves . Yuav ua li cas ob tog symmetry tso cai rau txhais lus nug?
Puas yog caij nyoog tshwm sim los ntawm kev ua ntej ntawm lub ntiaj teb axis?
Lub caij nyoog puas yuav nyob zoo ib yam? Tsis yog, vim txoj kev taw qhia ntawm lub ntiaj teb axis hloov lub sijhawm. Qhov no yog hu ua Precession, uas yog lub voj voog ncig ntawm lub ntiaj teb tilted axis thiab zoo ib yam li saum lub wobble thaum nws qeeb .
Puas yog axis ntawm symmetry thiab kab ntawm symmetry tib yam?
kab ntawm symmetry tseem hu ua daim iav kablossis axis ntawm symmetry. Lub voj voog muaj cov kab tsis kawg ntawm kev sib luag . Qhov txawv ntawm axis ntawm symmetry thiab kab ntawm symmetry yog dab tsi? Ib kab los ntawm cov duab kom txhua sab yog daim iav duab.
Ntawm axis ntawm symmetry?
Lub axis ntawm symmetry yog txoj kab ntsug uas mus los ntawm vertex ntawm parabolayog li sab laug thiab sab xis ntawm parabola yog sib luag. Kom ua kom yooj yim, kab no faib cov duab ntawm ib qho kev sib npaug rau hauv ob daim iav . Koj pom qhov axis ntawm symmetry li cas?
Yuav ua li cas xam qhov nrawm los ntawm ib qho loj axis?
Lub semi loj axis yog ib qho yooj yim. Nws tau txiav txim los ntawm Equation 9.5. 31: V2=GM(2r−1a) . Yuav ua li cas koj pom qhov nrawm ntawm ib nrab-axis loj? The semi-major axis, denoted a, is so given by a=12(r1+r2) a=1 2 (r 1 + r 2).
