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 tsim, Rene Descartes.
Tsis tas li, lwm lub npe rau lub dav hlau Cartesian yog dab tsi?
Ib tug Euclidean dav hlau nrog ib tug xaiv Cartesiancoordinate system npe a Cartesianplane.
Tsis tas li ntawd, vim li cas nws thiaj hu ua Cartesian dav hlau? Cov Cartesian dav hlau qee zaum hu ua asthe x-y dav hlau los yog cov tswj lub dav hlau thiab yog siv toplot cov ntaub ntawv khub ntawm ob kab kab. Cov Cartesian dav hlau yog npe tom qab tus lej lej Rene Descartes uas tau pib nrog lub tswvyim. Cartesian dav hlau yog tsim los ntawm ob kab perpendicular kab sib tshuam.
Ib yam li ib tug yuav nug, dab tsi yog qhov ntawm Cartesian dav hlau?
X-axis thiab y-axis faib cov tswj lub dav hlau rau hauv plaub ntu npe quadrants. Qee zaum lawv tau sau npe siv cov lej Roman I, II, III, thiab IV. Lwm lub sij hawm lawv tau sau npe Q1, Q2, Q3, thiab Q4.
Muaj pes tsawg hom kev sib koom tes muaj?
Cylindrical thiab spherical kev tswj xyuas qhov system Muaj ob txoj hauv kev rau kev nthuav dav lub polar tswj qhov system mus rau peb qhov ntev.

Peb tus yam ntxwv dav dav ntawm cov hlau yog dab tsi?
Peb yam ntxwv ntawm cov hlau yog lawv cov conductivity zoo, malleability, thiab ci iab tsos. Cov hlau yog cov zoo conductors ntawm tshav kub thiab hluav taws xob
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
Yuav ua li cas lwm txoj hauv kev rau npe lub dav hlau?
Lwm lub npe rau dav hlau A yog dav hlau BCD thiab dav hlau CDE. b. Cov ntsiab lus C, E, thiab D nyob ntawm tib kab, yog li lawv yog collinear. Cov ntsiab lus B, C, E, thiab D nyob hauv tib lub dav hlau, yog li lawv yog coplanar
Lub dav hlau Cartesian rau menyuam yaus yog dab tsi?
Hauv kev ua lej, Cartesian coordinate system yog qhov kev sib koom ua ke siv los tso cov ntsiab lus ntawm lub dav hlau siv ob tus lej, feem ntau hu ua x-coordinate thiab y-coordinate. Txhawm rau tso cov kev sib koom ua ke, ob txoj kab sib txuas, hu ua axes (Singular: axis), raug kos
Lwm lub npe rau lub dav hlau ua haujlwm yog dab tsi?
Lub dav hlau ob sab yog hu ua Cartesian dav hlau, los yog lub dav hlau sib koom tes thiab cov axes yog hu ua kev sib koom tes axes lossis x-axis thiab y-axis. Lub dav hlau muab muaj plaub qhov sib npaug los ntawm keeb kwm hu ua quadrants
