Hauv lej, the Cartesian tswj qhov system yog a tswj qhov system siv los tso cov ntsiab lus rau a dav hlau siv ob tus lej, feem ntau hu ua x- koom tes thiab y- koom tes . Tso lub ua haujlwm , ob kab perpendicular, hu ua axes (Singular: axis), yog kos.
Yog li ntawd, lub dav hlau Cartesian yog dab tsi?
A Cartesian dav hlau (lub npe tom qab Fabkis tus lej lej Rene Descartes, leej twg formalized nws siv hauv lej) yog txhais los ntawm ob kab kab zauv: x-axis, uas yog kab rov tav, thiab y-axis, uas yog ntsug. Siv cov axes no, peb tuaj yeem ua tau piav ib qho point hauv lub dav hlau siv ib khub ntawm tus lej.
Ib yam li ntawd, koj ua lub dav hlau Cartesian li cas? Txhawm rau tsim lub dav hlau sib koom ua ke, peb ua raws li cov kauj ruam no:
- Kos ob tus lej kab perpendicular rau ib leeg, sib tshuam ntawm qhov taw tes 0 ntawm ob kab.
- Sau tus lej kab rov tav raws li x-axis thiab sau cov kab ntsug tus lej raws li y-axis.
Ntawm no, dab tsi yog lub dav hlau ua haujlwm rau cov menyuam yaus?
tswj lub dav hlau los yog Cartesian dav hlau . • a dav hlau muaj ob txoj kab nruab nrab (x thiab y) sib tshuam ntawm ib qho chaw hu ua keeb kwm (0, 0). • txoj hauj lwm yog denoted siv khub ntawm ua haujlwm , np. (2, 4).
Vim li cas Cartesian dav hlau tseem ceeb?
Nyob rau hauv nws hwm, lub kaw lus yog qee zaum hu ua tus Cartesian tswj qhov system . Cov tswj lub dav hlau tuaj yeem siv los sau cov ntsiab lus thiab cov kab kos. Qhov system no tso cai rau peb piav qhia txog kev sib raug zoo ntawm algebraic hauv kev pom kev pom, thiab tseem pab peb tsim thiab txhais cov ntsiab lus algebraic.

Dab tsi yog lub xeev txoj kev xav rau cov menyuam yaus?
Txoj kev ntseeg ruaj khov hais tias txawm tias lub qab ntuj khwb nthuav dav, txawm li cas los xij nws tsis hloov nws lub sijhawm. Txhawm rau ua qhov no, cov teeb meem tshiab yuav tsum tau tsim kom muaj qhov sib npaug sib npaug ntawm lub sijhawm
Dab tsi yog kev tswj xyuas hauv Cartesian dav hlau?
Cartesian coordinates ntawm lub dav hlau Lub hauv paus chiv keeb yog kev sib tshuam ntawm x thiab y-axes. Cartesian kev tswj hwm ntawm ib qho taw tes hauv lub dav hlau yog sau ua (x, y). X-coordinate qhia qhov kev ncua deb mus rau sab xis (yog tias x yog qhov zoo) lossis sab laug (yog tias x tsis zoo) ntawm y-axis
Dab tsi yog qhov chaw ntawm lub ntiajteb txawj nqus rau cov menyuam yaus?
Ib qho khoom nruab nrab ntawm lub ntiajteb txawj nqus yog qhov taw tes qhov hnyav txawm nyob rau txhua sab. Rau ib qho khoom sib npaug, zoo li lub pob lossis tus kav, qhov nruab nrab ntawm lub ntiajteb txawj nqus yuav nyob nruab nrab ntawm qhov khoom. Rau cov khoom tsis sib xws, zoo li koj thiab kuv, qhov nruab nrab ntawm lub ntiajteb txawj nqus tsis yog nyob rau hauv qhov chaw
Lwm lub npe ntawm Cartesian dav hlau yog dab tsi?
Thaum koj muab ob lub axes tso rau hauv lub dav hlau, nws hu ua 'Cartesian' ('carr-TEE-zhun') dav hlau. Lub npe 'Cartesian' yog muab los ntawm lub npe 'Descartes', tom qab nws tus tsim, Rene Descartes
Muaj pes tsawg quadrants nyob rau hauv lub dav hlau Cartesian?
plaub Ua li no, plaub lub quadrants ntawm lub dav hlau ua haujlwm yog dab tsi? Cov kev sib tshuam x- thiab y-axes faib cov tswj lub dav hlau rau hauv 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.
