Thawj quadrant yog lub ces kaum sab xis ntawm lub daim duab , seem uas ob qho tib si x thiab y yog qhov zoo. Qhov thib ob quadrant , nyob rau sab laug sab laug, suav nrog qhov tsis zoo ntawm x thiab qhov zoo ntawm y. Qhov thib peb quadrant , lub kaum sab laug sab laug, suav nrog qhov tsis zoo ntawm ob qho tib si x thiab y.
Yog li ntawd, dab tsi yog 4 quadrants ntawm daim duab?
Cov kev sib tshuam x- thiab y-axes faib lub dav hlau sib koom ua ke plaub ntu. Cov no plaub ntu hu ua quadrants . Quadrants muaj npe siv cov lej Roman I, II, III, thiab IV pib nrog rau sab xis quadrant thiab txav counterclockwise.
Ib yam li ntawd, cov ntsiab lus twg hauv daim duab nyob hauv Quadrant III? Lub axes ntawm ob-dimensional Cartesian system faib lub dav hlau sib koom ua plaub thaj tsam uas hu ua quadrants , txhua bounded los ntawm ob ib nrab-axes. Hauv daim duab muab rau hauv nqe lus nug Point E thiab N yog lus dag nyob rau hauv quadrant III . Yog li ntawd Point E thiab N yog lus dag nyob rau hauv quadrant III.
Ib yam li ntawd, koj tuaj yeem nug, qhov twg quadrant yog qhov twg?
Yog tias ib qho kev sib koom tes yog xoom, ces qhov taw tes yog nyob rau ntawm x- axis lub y- axis . Yog tias y coordinate yog xoom, ces lub ntsiab lus nyob rau ntawm y- axis . Yog hais tias ob qho tib si coordinates yog xoom, ces lub ntsiab lus sawv cev rau lub hauv paus chiv keeb. Cov cov axes e., x axis thiab y axis faib lub dav hlau coordinate ua plaub quadrants.
Dab tsi yog quadrant yog qhov point 00 hauv?
Nco ntsoov tias cov ntsiab lus uas dag ntawm ib tug axis tsis dag nyob rau hauv ib qho twg quadrant . Yog ib taw tes nyob rau ntawm x-axis ces nws y-coordinate yog 0 . Ib yam li ntawd, a taw tes ntawm y-axis muaj nws x-coordinate 0 . Lub hauv paus chiv keeb muaj coordinates ( 0 , 0 ).

Vim li cas nws thiaj li hais tias lub Orthocenter ntawm daim duab peb sab obtuse yuav tsum nyob rau sab nraud ntawm daim duab peb sab?
Nws hloov tawm tias tag nrho peb qhov siab ib txwm sib tshuam ntawm tib lub ntsiab lus - lub npe hu ua orthocenter ntawm daim duab peb sab. Lub orthocenter tsis yog ib txwm nyob hauv daim duab peb sab. Yog tias daim duab peb sab yog obtuse, nws yuav nyob sab nraud. Txhawm rau ua kom qhov no tshwm sim cov kab qhov siab yuav tsum tau txuas ntxiv kom lawv hla
Dab tsi yog qhov txawv ntawm daim duab thiab daim duab?
Ib daim duab yog ib daim duab ntawm kev ua lej, tab sis kuj siv tau (loos) txog ib daim duab ntawm cov ntaub ntawv txheeb cais.A daim duab yog ib daim duab sawv cev ntawm cov ntaub ntawv, qhov twg ib kab ntawv yog ib daim ntawv
Qhov kev hloov pauv twg yuav hloov daim duab A rau hauv daim duab B?
Ob daim duab tau hais tias yuav sib haum xeeb yog tias ib tus tuaj yeem tau txais los ntawm lwm tus los ntawm ib ntu ntawm kev txhais lus, kev xav, thiab kev sib hloov. Cov duab sib xws muaj qhov loj thiab zoo tib yam. Txhawm rau hloov daim duab A rau hauv daim duab B, koj yuav tsum xav txog nws hla y-axis thiab txhais ib chav nyob rau sab laug
Dab tsi yog qhov txawv ntawm lub xeev daim duab kos duab thiab daim duab ua haujlwm?
Lub xeev daim duab qauv yog siv los qhia qhov sib lawv liag ntawm lub xeev uas ib yam khoom mus dhau, qhov ua rau kev hloov ntawm ib lub xeev mus rau lwm qhov thiab qhov kev txiav txim uas tshwm sim los ntawm lub xeev hloov. Daim duab ua haujlwm yog ntws ntawm kev ua haujlwm yam tsis muaj qhov tshwm sim (kev tshwm sim) mechanism, lub xeev tshuab yog suav nrog lub xeev triggered
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
