Nws tau pom tias cov tub ntxhais kawm siv lub ntsuas phoo thiab ncaj ntug ua lej zoo dua thiab khaws cov uas lawv tau kawm. Tsis tas yuav tsum muaj cov tub ntxhais kawm siv lub ntsuas phoo thiab ncaj nraim, thiab tag nrho cov kev tsim kho geometric yuav tsum tau ua los ntawm kev kos duab.
Dab tsi yog qhov zoo ntawm kev siv lub compass thiab straightedge?
Dab tsi yog cov txiaj ntsig ntawm kev siv thev naus laus zis dhau lub ntsuas ntsuas ntsuas thiab ncaj? Technology muaj qee qhov zoo dua li lub xov tooj ntawm tes thiab ncaj nraim. Ua ntej tshaj plaws yog ntau qhov tseeb, nrawm dua, nrawm dua / huv (daim duab)thiab yog tias koj ua nws yog nws yuav zoo meej.
Nws puas yooj yim rau siv lub compass thiab straightedge?
Cov neeg Greek thaum ub tau xav tias cov teeb meem kev tsim kho lawv daws tsis tau tsuas yog ua tsis ncaj, tsis daws tsis tau. Nrog rau cov txheej txheem niaj hnub no, txawm li cas los xij, cov kev ncaj ncees thiab kev sib txuas ua ke tau pom tias yog qhov tsis muaj peev xwm ua tau.
Vim li cas thiaj tseem ceeb rau kev kawm kev tsim kho hauv geometry?
Tsis yog txhua tus uas nyiam lej nyiam lej. Geometric kev tsim kho tso cai rau koj los tsim cov kab, kaum sab xis, thiab polygons nrog qhov yooj yim ntawm cov cuab yeejKoj yuav xav tau ntawv, xaum ntse, ib qho ncaj los tswj koj cov kab (kom ua kom ncaj), thiab ib daim duab kos rau viav vias arcs thiab daim ntawv voj voog.
Vim li cas lub compass tseem ceeb hauv geometry?
Ib lub compass yog siv hauv kev ua lej, kos duab thiab kos duab los tsim arcs, voj voog lossis lwm cov duab geometric uas tuaj yeem txiav txim siab los ntawm kev ntsuas cov kab sib txuas. Lub compass tuaj yeem siv los ua ob kab, nrhiav cov ntsiab lus nruab nrab thiab pab daws teeb meem hauv geometry.

Yuav ntsuas ntsuas ntsuas ntsuas li cas?
Ib lub ntsuas hluav taws xob muaj peev xwm ntsuas tus nqi ntawm cov khoom tawg tag nrho (TDS) hauv cov tshuaj, hauv cov khoom ntawm ib lab (ppm) lossis milligrams ib liter. Tus qauv kev sib raug zoo ntawm TDS kev ntsuas ntawm kev daws teeb meem thiab kev ntsuas kev ntsuas yog:
Leej twg yog cov tub ntxhais kawm tshiab thiab cov kawm qib kaum ob?
Cov tub ntxhais kawm theem siab thawj xyoo yuav luag tsuas yog hu ua cov tub ntxhais kawm tshiab, lossis qee zaum los ntawm lawv qib xyoo, qib 9. cov tub ntxhais kawm xyoo ob yog cov kawm sophomores, lossis qib 10, tom qab ntawv juniors lossis 11th, thiab thaum kawg cov laus lossis qib 12 .
Kev coj ncaj ncees pab rau cov tub ntxhais kawm kev kawm li cas?
Txoj kev taw qhia, kev cia siab, thiab kev kawm: Cov teeb meem cuam tshuam hauv cov cheeb tsam no cuam tshuam ncaj qha rau kev nyeem ntawv nkag siab thiab koj lub peev xwm nyeem tau zooLawv kuj cuam tshuam rau kev paub txog thaj chaw thiab koj lub peev xwm los saib lub hlwb.
Dab tsi txawv ntawm tus tub ntxhais kawm tshiab thiab cov tub ntxhais kawm tshiab tshiab?
Lub sij hawm redshirt freshman qhia txog kev kawm sophomore uas yog lawv thawj lub caij sib tw kis las. Ib tug tub ntxhais kawm ntawv tshiab yog qhov txawv ntawm ib tug neeg kawm tshiab: tus menyuam kawm ntawv uas nyob hauv lawv thawj xyoo ob qho kev kawm thiab kis las .
Cov tub ntxhais kawm qib 3 yuav tsum paub qhov sib npaug?
Multiplication & Division. Thaum kawg ntawm qib peb, koj tus menyuam yuav tsum muaj tag nrho lawv qhov sib npaug thiab faib qhov tseeb (txog 100) cim Hauv qib plaub, cov tub ntxhais kawm txuas ntxiv qhov kev nkag siab no thiab pib suav ob thiab peb tus lej sib npaug thiab faib teeb meem .
