Perpendicular kab thiab Lawv Qhov chaw siab
Cov qhov chaw siab tshaj ntawm ob kab perpendicular yog cov tsis zoo reciprocals ntawm ib leeg. Qhov no txhais tau tias yog a kab yog perpendicular rau a kab uas muaj txoj kab nqes m, tiam txoj kab nqes ntawm kab yog -1 / m. Piv txwv li, peb pom tias lub txoj kab nqes ntawm kab y = (1/2) x + 3 = 1/2.
Ib yam li ntawd, txoj kab nqes ntawm kab perpendicular rau kab no yog dab tsi?
A kab perpendicular rau lwm tus muaj a txoj kab nqes uas yog qhov tsis zoo reciprocal ntawm txoj kab nqes ntawm lwm tus kab . Qhov tsis zoo reciprocal ntawm tus thawj kab yog -2, thiab yog li ntawd txoj kab nqes ntawm nws kab perpendicular.
Tom qab, lo lus nug yog, ua li cas koj nrhiav tau ib txoj kab nqes perpendicular? Rau nrhiav tus txoj kab nqes ntawm kab uas peb yuav tsum tau mus rau hauv kab txoj kab nqes -intercept form (y = mx + b), uas txhais tau tias peb yuav tsum tau daws rau y: The txoj kab nqes 4x – 5y = –10 m = 4/5. Yog li ntawd, lub txoj kab nqes ntawm kab perpendicular rau kab no yuav tsum yog m = -5/4. Kauj ruam 2: Siv lub txoj kab nqes rau nrhiav lub y-intercept.
Ib yam li ntawd, yuav ua li cas cov nqes hav ntawm kab perpendicular piv?
Parallel kab muaj ib yam txoj kab nqes thiab yuav tsis sib tshuam. Parallel kab txuas ntxiv, lus, mus ib txhis tsis kov (xav tias cov no kab nyob rau tib lub dav hlau). Ntawm qhov tod tes, lub txoj kab nqes ntawm kab perpendicular yog cov tsis zoo reciprocals ntawm ib leeg, thiab ib khub ntawm no kab sib tshuam ntawm 90 degrees.
Thaum ob kab yog perpendicular Qhov nqes hav yog?
Perpendicular kab yog kab uas sib tshuam ntawm txoj cai kaum. Yog koj multiply txoj kab nqes ntawm ob kab perpendicular hauv lub dav hlau, koj tau txais −1. Ntawd yog, lub qhov siab ntawm kab perpendicular yog opposite reciprocals.

Qhov nqes hav ntawm kab perpendicular rau Y2 yog dab tsi?
Perpendicular kab yeej ib txwm pom los ntawm reciprocating tus nqi tsis zoo ntawm txoj kab nqes hauv nqe lus nug. Qhov nqes hav hauv qhov no, hauv y = 2, yog xoom
Dab tsi yog qhov khoom ntawm txoj kab nqes ntawm kab perpendicular?
Yog hais tias ob kab yog perpendicular, cov nqes hav yog tsis zoo reciprocals. (Cov khoom ntawm qhov nqes hav = -1.) txij li thaum lawv qhov nqes hav ntawm 0 muaj undefined reciprocals
Qhov nqes hav ntawm qhov kev txiav txim xoom yog dab tsi?
Rate Laws from Graphs of Concentration Versus Time (Integrated Rate Laws) Rau qhov kev txiav txim xoom, tus nqi = k (k = - nqes hav ntawm kab) Rau qhov kev txiav txim thib 1, tus nqi = k [A] (k = - nqes hav ntawm kab) Rau qhov kev txiav txim thib 2, tus nqi = k[A]2 (k = nqes hav ntawm kab)
Dab tsi yog txoj kab nqes kev sib raug zoo ntawm kab perpendicular?
Muab qhov no ua ke nrog cov kev hloov pauv, thiab koj tau txais tias txoj kab nqes ntawm txoj kab nruab nrab yog qhov 'tsis zoo reciprocal' ntawm txoj kab nqes ntawm thawj kab - thiab ob kab nrog txoj kab nqes hav uas tsis zoo reciprocals ntawm ib leeg yog perpendicular rau ib leeg
Yuav ua li cas koj nrhiav tau txoj kab nqes ntawm ib tug parallel thiab perpendicular kab?
Txhawm rau nrhiav txoj kab nqes ntawm txoj kab no peb yuav tsum tau txais txoj kab rau hauv txoj kab nqes-intercept daim ntawv (y = mx + b), uas txhais tau tias peb yuav tsum tau daws rau y: Qhov nqes hav ntawm kab 4x - 5y = 12 yog m = 4 / 5. Yog li ntawd, txoj kab nqes ntawm txhua kab uas tig mus rau kab no yuav tsum yog m = 4/5. Ob kab yog perpendicular yog tias
