Peb ua tau txiav txim los ntawm lawv equations seb ob kab yog thaum uas tig mus los ntawm kev sib piv lawv txoj kab nqes. Yog cov nqes hav yog tib yam thiab cov y-intercepts txawv, cov kab yog thaum uas tig mus . Yog cov nqes hav txawv, cov kab tsis yog thaum uas tig mus . Tsis zoo li thaum uas tig mus kab, kab perpendicular ua kev sib tshuam.
Cov neeg kuj nug, koj ua pov thawj li cas ib kab yog parallel rau ib qho kev sib npaug?
Ob kab yog parallel yog tias muaj tib txoj kab nqes. Piv txwv 1: Nrhiav txoj kab nqes ntawm lub kab parallel mus rau kab 4x – 5y = 12. Kom nrhiav tau txoj kab nqes ntawm no kab peb yuav tsum tau kab rau hauv nqes hav-intercept daim ntawv (y = mx + b), uas txhais tau tias peb yuav tsum tau daws rau y: Txoj kab nqes ntawm lub kab 4x – 5y = 12 m = 4/5.
Qhov thib ob, qhov piv txwv perpendicular yog dab tsi? Perpendicular - Txhais nrog Piv txwv Ob kab sib txawv ntawm ib leeg ntawm 90 ° lossis lub kaum sab xis yog hu ua perpendicular kab. Piv txwv : AB is perpendicular rau XY vim AB thiab XY sib tshuam ntawm 90 °. Tsis- Piv txwv : Ob kab yog sib npaug thiab tsis sib tshuam.
Ntxiv rau qhov no, piv txwv li cov kab sib luag yog dab tsi?
Parallel kab yog ob lossis ntau dua kab uas yeej tsis sib tshuam. Piv txwv ntawm cov kab sib txuas nyob ib ncig ntawm peb, hauv ob sab ntawm nplooj ntawv no thiab hauv rhawv ntawm lub thawv ntawv.
Koj ua pov thawj li cas cov kab yog perpendicular?
Lub linear khub perpendicular theorem hais tias thaum ob ncaj kab intersect ntawm ib tug taw tes thiab tsim ib tug linear khub ntawm vaj huam sib luag kaum, lawv yog perpendicular . Ib khub ntawm cov ces kaum yog xws li cov sum ntawm cov ces kaum yog 180 degrees. Raws li cov ces kaum ntsuas 90 degrees, lub kab muaj pov thawj los ua perpendicular rau ib leeg.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Koj tuaj yeem ua li cas yog tias koj tsis paub tias txheej twg yog nyob rau hauv cov txheej txheem rho tawm?
Koj tuaj yeem ua li cas yog tias koj tsis paub tias txheej twg yog nyob rau hauv cov txheej txheem rho tawm? Tso dej me me rau hauv lub caj dab ntawm qhov sib cais funnel. Ua tib zoo saib nws: yog tias nws tseem nyob hauv txheej txheej sab saud, txheej txheej ntawd yog txheej dej
Koj tuaj yeem qhia tau li cas tias lub pob zeb twg yog qhov qub tshaj plaws?
Lub hauv paus ntsiab lus ntawm superposition hais tias cov pob zeb qub tshaj plaws nyob rau hauv qab, thiab tus yau tshaj yog nyob rau saum. Raws li qhov no, txheej C yog qhov qub tshaj plaws, ua raws li B thiab A. Yog li tag nrho cov txheej xwm raws li hauv qab no: Txheej C tsim
Koj tuaj yeem qhia tau li cas yog tias kev sib raug zoo yog symmetrical?
Ib qho kev sib raug zoo yog qhov sib luag yog tias, peb pom tias rau txhua qhov txiaj ntsig ntawm a thiab b: a R b implies b R a. Kev sib raug zoo ntawm kev sib npaug dua yog symmetrical. Yog tias x = y, peb tuaj yeem sau tias y = x thiab
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
