Microsoft lej? cov cuab yeej zoo rau cov tub ntxhais kawm (3)

Peb txuas ntxiv kawm paub siv qhov zoo tshaj plaws (Kuv nco koj: dawb los ntawm version 4) Microsoft Mathematics program. Peb pom zoo hu nws yooj yim MM luv luv. Ib qho nthuav heev ntawm MM yog lub peev xwm ua noj? animation thiab? nto graphs los yog ua lwm yam lus? graphs ntawm kev ua haujlwm ntawm ob qhov sib txawv. Peb mam li pib kawm yuav ua li cas ua qhov no siv Cartesian kev tswj hwm ib txwm, thiab pib los ntawm kev kos duab sawv cev rau qhov chaw ntawm plaub? cia peb hais cov ntsiab lus. Peb ua raws li hauv qab no: Nyem rau ntawm kab ntawv tab. Peb tab tom nthuav dav "Cov Ntaub Ntawv Teeb" kev xaiv. Xaiv 3D los ntawm Dimensions daim ntawv teev npe. Los ntawm Daim Ntawv Coordinates, xaiv Cartesian. Nyem qhov Insert Dataset khawm. Nyob rau hauv lub "Paste Dataset" dialog box, peb muab tshuaj txhuam tus coj peb Cartesian coordinates ntawm peb plaub lub ntsiab lus. Nyem Graph. Nco ntsoov tus lej? ntxig los ntawm tsuas yog ntaus ob tsab ntawv ntawm cov keyboard: pi.

Ua tib zoo saib cov cim hauv lub qhov rais saum toj no. Braces? raws li koj tau pom? MMs yog siv ob qho tib si los xaiv ib lub teeb (hauv qhov no: ib pawg ntawm peb lub ntsiab lus hauv qhov chaw peb sab), thiab xaiv qhov taw tes los ntawm kev sau nws cov kev tswj hwm. Txij li thaum MM yog ib qho kev pabcuam Asmeskas, cov lej tseem raug cais tawm ntawm cov lej tsis yog los ntawm tus lej cim, raws li peb muaj nyob hauv tebchaws Poland, tab sis los ntawm qhov chaw.

Ua hauj lwm nrog cov kev pab cuam, cia peb sim mus ntes cov txiaj ntsig duab nrog tus nas (nyem rau ntawm nws thiab tuav lub pob laug nas) thiab txav peb "Rodent"; peb yuav pom tias daim duab tuaj yeem tig tau. Thaum peb teem nws rau lub kaum sab xis xaiv, nrog rau kev xaiv "Txuag daim duab li duab" peb tuaj yeem txuag nws li duab png.

Tsis tas li ntawd nco ntsoov tias lub toolbar qhia nyob rau hauv daim duab txuas nrog daim ntawv qhia formatting commands. Hauv particular, koj tuaj yeem nkaum qhov kev sib koom tes axes thiab tus ncej uas tag nrho cov duab muab tso rau. Nws yog lub sijhawm los npaj thaj chaw. Nov yog daim ntawv tshuaj:

• Nyem qhov Graph tab.
• Nthuav Equations thiab Functions.
• Xaiv 3D los ntawm Dimensions daim ntawv teev npe.
• Nyem rau ntawm thawj lub vaj huam sib luag uas tshwm.
• Nyob rau hauv lub qhov rais tawm tswv yim uas tshwm sim, nkag mus rau qhov tsim nyog muaj nuj nqi (qhov no tuaj yeem ua tiav siv cov keyboard lossis siv tus nas thiab cov chaw taws teeb tswj ntawm sab laug)
• Nyem Graph.

Lub implicit muaj nuj nqi yog tau pom nyob rau hauv lub sab saum toj qhov rais.

Lawm, tam sim no peb muaj peev xwm tig tau dawb dov daim duab nrog tus nas, nkaum cov thav ntawv thiab cov kev tswj hwm, thiab lwm yam. Thiab yuav ua li cas thaum tsis muaj -1, tab sis qee qhov parameter ntawm sab xis ntawm kab zauv? Piv txwv li? Cia peb sim (tam sim no peb yuav qhia tsuas yog ib feem ntawm lub qhov rais ua haujlwm kom pom tseeb dua):

Daim ntawv ceeb toom tias Daim Ntawv Qhia Tswj Vaj Huam Sib Luag tam sim no (tsis siv neeg) tshwm nrog kev xaiv Animation. Hauv qab no peb muaj ib qho parameter (qhov no a, uas tsis yog qhov xav tsis thoob, vim peb hu nws tias peb tus kheej?), uas peb tuaj yeem hloov nrog slider thiab saib xyuas qhov tshwm sim. Los ntawm nias lub ?kab xev? ib sab ntawm lub slider yuav pib cov animation zoo li ib tug yeeb yam.

Tsis muaj laj thawj tsis saib ob lossis ntau qhov chaw sib koom ua ke. Txhawm rau ua qhov no, hauv Graphing qhov rai, tsuas yog ntxiv lwm qhov kev ua haujlwm kho qhov rai, nkag mus rau qhov sib npaug tsim nyog thiab nyem rau ntawm Graph hais kom ua. Hauv peb qhov piv txwv, peb tau ntxiv qhov sib npaug nrog cov parameter

tau txais (tom qab ua qhov tsim nyog kev sib hloov thiab hloov cov zaub siv Xim Nto / Wireframe khawm ntawm lub cuab yeej ribbon) qee yam xws li:

Raws li koj tau pom, cov animation tswj tam sim no kuj muaj. Tau kawg, txoj haujlwm los tig daim ntawv nrog tus nas ua haujlwm txhua lub sijhawm. MM yooj yim tuav dab tsi ntau dua li Cartesian? Kab txawv? tswj systems. Peb kuj muaj kheej kheej thiab cylindrical coordinate systems. Nco qab tias ib qho chaw nyob rau hauv spherical coordinates yog piav los ntawm kev sib npaug ntawm hom

uas yog, lub thiaj li hu ua lead radius r yog qhia nyob rau hauv cov ntaub ntawv no raws li ib tug muaj nuj nqi ntawm ob lub kaum sab xis; Yog tias peb xav siv cylindrical coordinates, peb yuav tsum siv qhov sib npaug hais txog Cartesian sib txawv rau cov ri?

Piv txwv li, cia peb saib cov duab ntawm lub luag haujlwm z = Okay? thiab tom qab ntawd tsis rov qab mus rau lub ntsiab lus ntawm cov duab ntawm cov haujlwm thiab qhov chaw? Wb kuj hais tias nyob rau hauv ob-dimensional rooj plaub peb muaj nyob rau ntawm peb pov tseg tsis tau tsuas yog lub Cartesian system, tab sis kuj yog ib tug polar, uas yog tshwj xeeb tshaj yog zoo haum rau depicting txhua yam ntawm ca spirals.
