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?
X -coordinate ntawm lub vertex yog qhov sib npaug ntawm axis ntawm symmetry ntawm parabola. Rau ib tug quadratic muaj nuj nqi nyob rau hauv tus qauv daim ntawv, y=ax2 + bx + c, axis ntawm symmetry yog ib tug ntsug kab x=−b2a.
Koj pom qhov vertex ntawm axis ntawm symmetry li cas?
Daim ntawv Vertex ntawm ib qho kev ua haujlwm plaub yog muab los ntawm: f(x)=a(x−h)2+k, qhov twg (h, k) yog Vertex ntawm parabola. x=h yog axis ntawm symmetry. Siv ua kom tiav txoj kev square los hloov f(x) rau hauv Vertex Form.
Dab tsi yog qhov axis ntawm symmetry piv txwv?
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.
Dab tsi taw tes nyob ntawm qhov axis ntawm symmetry?
Tus vertex yog qhov taw tes siab tshaj yog tias tus parabola qhib downward thiab qhov qis tshaj yog tus parabola qhib upward. Lub axis ntawm symmetry yog txoj kab uas txiav cov parabola rau hauv 2 qhov sib txuam halves thiab lub vertex nyob ntawm axis ntawm symmetry.

Yuav tsum ntsuas kub ntawm x lossis y axis?
Koj yuav raug qhia tias lub axis twg siv rau qhov txawv txav.) Yog tias koj tau hais kom ua ib daim duab ntawm "kub vs. sijhawm", txhais tau tias kub yog nyob rau ntawm y-axisthiab lub sijhawm nyob ntawm x-axis . Dab tsi yuav tsum yog ntawm x thiab y-axis?
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.
Rau dav hlau ntawm symmetry?
Ib dav hlau ntawm symmetry yog ib lub dav hlau xav txog uas faib cov molecule rau hauv ib nrab uas yog iav dluab ntawm ib leegpiv txwv. … Hauv 1, lub dav hlau ntsug uas faib cov methyl pawg, cov pa roj carbon atom, thiab hydrogen atom faib cov molecule rau hauv ib nrab uas yog daim iav duab ntawm ib leeg .
Los ntawm axis ntawm symmetry txhais?
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.
