Microsoft Mathematics yog ib qho cuab yeej zoo rau cov tub ntxhais kawm (1)

Lub tuam txhab Bill Gates (txawm tias nws twb yog "tus neeg ntiag tug", tab sis tom qab tag nrho nws qhov tsis tuaj yeem "lub ntsej muag") tsis ntev los no tau tshaj tawm hauv Is Taws Nem cov cuab yeej zoo ntawm hom no, uas cov kws tshawb fawb hauv computer hu ua CAS (Computer Algebra System? Computer Algebra System) ). ). Muaj ntau cov cuab yeej muaj zog tshaj tawm muaj, tab sis qhov no zoo li tshwj xeeb tshaj yog haum rau cov tub ntxhais kawm cov kev xav tau? thiab txawm yog ib tug tub kawm ntawv ntawm ib lub tsev kawm txuj ci. MM tuaj yeem daws txhua qhov sib npaug, cov phiaj xwm ua haujlwm ntawm ib lossis ob qhov sib txawv, sib txawv thiab sib xyaw ua ke, thiab muaj ntau yam kev txawj ntse, uas peb yuav tham txog tom qab.

Nws ua kev suav suav ob tus lej (ntawm tus lej tiag thiab cov lej) thiab cim, hloov cov qauv raws li. Nws yog ib qho tseem ceeb uas nws tsis tau nqis los tshaj tawm qhov kawg tshwm sim, tab sis sawv cev rau cov kev suav nruab nrab nrog kev ncaj ncees; qhov no txhais tau hais tias nws yog qhov zoo tagnrho rau kev tuav txhua yam haujlwm hauv tsev. Qhov kev txwv nkaus xwb yog koj yuav tsum paub lus Askiv. Zoo, eh? lej? Lus Askiv tsuas yog ob peb puas lo lus xwb?

Qhov kev zov me nyuam hu ua Microsoft Mathematics, nws tau siv los them nqi txog 20 las, txij li plaub version nws yog dawb kiag li. Muaj. Txawm li cas los xij, ua ntej ua qhov no, xyuas kom koj lub computer ua tau raws li qhov yuav tsum tau ua ua ntej; thiab lawv yog raws li nram no: kev khiav hauj lwm qhov tsawg kawg nkaus Windows XP nrog Service Pack 3 (tau kawg, nws tuaj yeem yog Vista lossis Windows 7), Microsoft .NET Framework 3.5 SP1 ntsia, processor nrog lub moos ceev ntawm 500 MHz (tsawg kawg) lossis 1. GHz (pom zoo), 256 MB yam tsawg kawg nkaus RAM (500 MB lossis ntau dua pom zoo), daim npav video nrog tsawg kawg 64 MB ntawm lub cim xeeb sab hauv, tsawg kawg 65 MB ntawm qhov chaw dawb disk.

Cov no tsis yog qhov tshwj xeeb loj, yog li tom qab rub tawm cov ntaub ntawv teeb tsa los ntawm qhov chaw nyob, peb mus rau banal installation thiab khiav qhov program.

Lub qhov rais ua haujlwm hauv qab no yuav tshwm sim:

Qhov tseem ceeb tshaj plaws ntawm sab xis: muaj ob lub qhov rais uas yuav khoob thaum koj qhib qhov program. Nyob rau hauv qab heev (dawb, nqaim, nrog tsab ntawv? Thiab?) muaj cov ntaub ntawv qhov rais, tiag tiag tsis tsim nyog, txawm hais tias nyob rau hauv lub chav kawm ntawm kev xam nws muaj cov lus piav qhia thiab cov lus qhia; thib ob? formula input window, peb puas tuaj yeem ua nws ob qho tib si los ntawm cov keyboard thiab siv "chaw taws teeb"? nrog cov nyees khawm; nyob rau hauv cov ntaub ntawv ntawm xaiv lub xeem lub cuab tam los ua hauj lwm nrog cov kev pab cuam, koj tsuas xav tau ib tug nas. Cov txiaj ntsig suav? Koj puas txhais tau cov qauv hloov dua siab tshiab lossis cov duab sib thooj? lawv tshwm nyob rau hauv lub qhov rais thib ob ntawm qhov chaw ua haujlwm, pib grey, nrog lub npe "Worksheet"; Nws yog ib nqi sau cia hais tias nyob ib sab ntawm lub tab nrog no inscription muaj ib tug "Chat" tab, uas peb yuav siv. Nws yooj yim npaum li cas los twv? thaum peb xav kawm cov duab ua haujlwm.

Thaum pib kawm qhov kev pab cuam interface, koj yuav tsum xyuam xim rau peb qhov chaw qhia los ntawm cov xub hauv daim duab txuas. Qhov no yog lub pob rau xaiv qhov chaw xam ("Teeb" rau cov lej tiag lossis "Complex" rau cov lej nyuaj); lub qhov rais "Decimal qhov chaw", uas yog, teeb tsa qhov tseeb ntawm kev suav (tus lej ntawm cov lej lej; nws yog qhov zoo tshaj kom tawm "Tsis tas" - tom qab ntawd lub computer yuav xaiv qhov tseeb nws tus kheej); Thaum kawg, lub Equation Solver khawm, thaum nias, lub khoos phis tawj yuav txheeb xyuas cov qauv nkag thiab, tejzaum nws, daws qhov sib npaug. Cov nyees khawm tseem yuav tsum tau tso tseg tsis hloov rau tam sim no (ib qho ntawm lawv, sau tias "Ink", tsuas yog siv tau rau cov khoom siv touchscreen nkaus xwb).

Nws yog lub sijhawm los ua thawj qhov kev suav.

Cia peb daws qhov kev sib npaug plaub npaug

x²-4=0

Txoj Kev 1 ntawm kev nkag mus ua haujlwm: Muab tus cursor tso rau hauv lub thawv ntawv qhia zaub mov thiab nias lub x, ^, -, 4, =, 0 cov yuam sij hauv ib ntus, Nco ntsoov tias thaum siv lub ^ cim ua lub cim rau kev nthuav tawm, yuav siv lub xub nce siab.

Txoj Kev 2 txhawm rau nkag mus ua haujlwm: ntawm qhov chaw taws teeb tswj? ntawm sab laug peb nias qhov sib txawv x, kos npe exponentiation ^ thiab cov yuam sij txuas ntxiv.

Nyob rau hauv ob qho tib si, ntawm chav kawm, peb qhov sib npaug yuav tshwm sim nyob rau hauv lub qhov rais qhov rai. Tam sim no nias tus yuam sij Enter. mus rau sab xis ntawm qhov chaw nkag? thiab nyob rau hauv lub qhov rais tshwm sim nyob rau sab saum toj muaj cov ntaub ntawv hais txog cov hauj lwm nyob rau hauv lub program lus:

Solvex²-4 = 0, x

uas txhais tau hais tias " daws qhov sib npaug hauv kab lus nrog kev hwm"), thiab hauv qab no yog peb kab nrog xiav pluses cim ua "kev daws teeb meem". Qhov no txhais tau hais tias qhov kev zov me nyuam tau pom peb txoj hauv kev los daws qhov teeb meem thiab tso peb nrog kev xaiv uas peb xav qhia (peb tuaj yeem, tau kawg, pom lawv txhua tus). Qhov kev pab cuam hauv qab no teev ob yam.

Piv txwv li, cia peb tsim txoj kev daws teeb meem thib ob. Nov yog qhov peb yuav pom ntawm qhov screen:

Raws li koj tau pom, qhov kev pab cuam qhia tau hais tias nws ntxiv 4 rau ob sab ntawm kab zauv, ces muab lub hauv paus square, coj nws nrog ntxiv thiab rho? thiab sau cov kev daws teeb meem. Puas yog nws txaus los luam txhua yam rau hauv notepad? thiab ua homework.

Tam sim no xav tias peb xav tau ib daim duab ntawm kev ua haujlwm

y = x²-4

Peb ua qhov no: hloov qhov screen saib mus rau "Graph". Lub qhov rais nkag qhov sib npaug yuav tshwm; peb tuaj yeem sau ntau qhov sib npaug ntawm ib qho los saib seb lawv cuam tshuam li cas rau ib leeg. Thaum xub thawj, tsuas yog teb rau nkag mus rau ob yog qhia, tab sis peb tsuas yog nkag mus rau ib qho hauv qhov ntxoov ntxoo. Peb puas tuaj yeem siv cov keyboard, lossis? zoo li ua ntej? los ntawm cov chaw taws teeb tswj. Tom qab ntawd nyem lub pob "Graph". ? thiab ib daim duab yuav tshwm sim, ib yam li hauv daim duab txuas nrog.

Nws yog tsim nyog sau cia tias tom qab xaiv lub qhov rais graphics, cov ntawv qhia zaub mov ribbon yuav hloov thiab peb yuav ua tau ntau yam formatting ntawm daim ntawv. Yog li peb tuaj yeem ua kom zoom hauv lossis tawm, nkaum cov axes, zais ciam teb sab nraud, nkaum daim phiaj. Peb kuj tuaj yeem txiav txim siab qhov sib txawv ntawm qhov tsis sib xws ntawm qhov pom thiab txuag cov txiaj ntsig tau los ua ib qho duab hauv ntau hom duab nrov tshaj plaws. Nyob rau hauv qab ntawm qhov sib npaug thiab muaj nuj nqi? kuj tseem muaj qhov kev xaiv nthuav dav rau kev nthuav tawm cov animation tswj ntawm "Graph Controls" daim ntawv; Kuv qhia koj kom kuaj xyuas cov txiaj ntsig ntawm lawv siv.

Lwm yam nta ntawm qhov kev zov me nyuam? tom ntej no.
