Masamu a Microsoft ndi chida chabwino kwa wophunzira (1)

Kampani ya Bill Gates (ngakhale ali kale "munthu payekha", koma pambuyo pake ndi "nkhope" yake yosasinthika) posachedwapa anaika pa intaneti chida chachikulu chamtunduwu, chomwe asayansi apakompyuta amachitcha CAS (Computer Algebra System? Computer Algebra System) ). ). Pali zida zamphamvu kwambiri kunja uko, koma kodi izi zikuwoneka kuti ndizofunikira kwambiri pazosowa za wophunzira? ndipo ngakhale wophunzira wa kuyunivesite yaukadaulo. MM akhoza kuthetsa equation iliyonse, ntchito zachiwembu zamitundu imodzi kapena ziwiri, kusiyanitsa ndi kuphatikizira, ndipo ali ndi maluso ena ambiri, omwe tidzakambirana pambuyo pake.

Imawerengera mowirikiza (pa manambala enieni ndi ovuta) komanso mophiphiritsira, kusintha ma formula moyenerera. Ndikofunikira kuti sichibwera popereka zotsatira zomaliza, koma imayimira mawerengedwe apakatikati ndi zifukwa; izi zikutanthauza kuti ndi yabwino kusamalira mitundu yonse ya ntchito zapakhomo. Choletsa chokha ndichakuti muyenera kudziwa Chingerezi. Chabwino, eh, masamu? Chingerezi ndi mawu mazana ochepa chabe?

Pulogalamuyi imatchedwa Microsoft Mathematics, idawononga pafupifupi madola 20, popeza mtundu wachinayi ndi waulere. Pali . Komabe, musanachite izi, onetsetsani kuti kompyuta yanu ikukwaniritsa zofunikira; ndipo iwo ali motere: opaleshoni dongosolo osachepera Windows XP ndi Service Pack 3 (kumene, kungakhale Vista kapena Windows 7), Microsoft .NET Framework 3.5 SP1 anaika, purosesa ndi wotchi liwiro 500 MHz (osachepera) kapena 1 GHz (ovomerezeka), 256 MB osachepera RAM (500 MB kapena kuposa akulimbikitsidwa), khadi kanema ndi osachepera 64 MB ya mkati kukumbukira, osachepera 65 MB free disk space.

Izi sizofunikira kwenikweni, kotero titatha kutsitsa fayilo yoyika ku adilesi yomwe tapatsidwa, timapita ku banal ndikuyendetsa pulogalamuyo.

Zenera lotsatirali la ntchito liziwoneka:

Chofunika kwambiri kumanja: pali mazenera awiri omwe adzakhala opanda kanthu mukatsegula pulogalamuyi. Pansi kwambiri (yoyera, yopapatiza, ndi kalata? Ndipo?) Pali zenera lachidziwitso, kwenikweni zosafunika, ngakhale powerengera zili ndi mafotokozedwe ndi malangizo; chachiwiri? zenera lolowetsa fomula, kodi tingathe kuchita zonse kuchokera pa kiyibodi ndikugwiritsa ntchito "kutali"? ndi mabatani; posankha chida chomaliza kuti mugwire ntchito ndi pulogalamuyi, mumangofunika mbewa. Chotsatira chowerengera? mukutanthauza mafomu osinthidwa kapena graph yofananira? amawonekera pawindo lachiwiri la malo ogwirira ntchito, poyamba imvi, ndi dzina lakuti "Worksheet"; Ndizofunikira kudziwa kuti pafupi ndi tabu yokhala ndi zolembedwazi pali tabu ya "Tchati", yomwe tidzagwiritse ntchito. ndikosavuta kulingalira bwanji? pamene tikufuna kuphunzira ntchito ma graph.

Mukamawerenga mawonekedwe a pulogalamuyo, muyenera kulabadira magawo atatu omwe akuwonetsedwa ndi mivi pachithunzi chophatikizidwa. Ili ndi batani losankha malo owerengera ("Real" pa manambala enieni kapena "Complex" ya manambala ovuta); zenera "Decimal malo", ndiye kukhazikitsa kulondola kwa mawerengedwe (chiwerengero cha malo decimal; ndi bwino kusiya "Osakhazikika" - ndiye kompyuta kusankha kulondola yokha); Pomaliza, batani la Equation Solver, likakanikizidwa, kompyuta imasanthula mafomu omwe adalowetsedwa, ndipo, mwina, kuthetsa ma equation. Mabatani otsalawo akuyenera kusiyidwa osasinthika pakadali pano (imodzi mwa iwo, yolembedwa "Ink", ndiyothandiza pazida zongokhudza pazenera).

Yakwana nthawi yoti muwerenge zoyamba.

Tiyeni tithetse ma quadratic equation

x²4 = 0

Njira 1 yolowera ntchito: Ikani cholozera m'bokosi lolowetsamo fomula ndikusindikiza makiyi x, ^, -, 4, =, 0. Dziwani kuti mukamagwiritsa ntchito chizindikiro ^ monga chizindikiro cha exponentiation, muvi wopita mmwamba udzagwiritsidwa ntchito.

Njira 2 yolowera ntchito: pa remote control? kumbali yakumanzere timakanikiza chosinthika x, chizindikiro chofotokozera ^ ndi makiyi ogwirizana nawo.

Muzochitika zonsezi, ndithudi, equation yathu idzawonekera pawindo lolowetsa fomula. Tsopano dinani batani la Enter. kumanja kwa malo olowetsamo? ndipo pazenera lazotsatira pamwamba pali mbiri yokhudza ntchitoyo muchilankhulo cha pulogalamuyo:

Solvex²-4=0,p

kutanthauza "thetsani equation m'mabulaketi mwaulemu"), ndipo m'munsimu muli mizere itatu yokhala ndi ma pluses abuluu olembedwa kuti "masitepe othetsera". Izi zikutanthauza kuti pulogalamuyi yapeza njira zitatu zothetsera vutoli ndipo zimatisiya ndi chisankho chomwe tikufuna kuwulula (tikhoza, ndithudi, kuwawona onse). Pulogalamu ili m'munsiyi imatchula zinthu ziwiri.

Mwachitsanzo, tiyeni tipange njira yachiwiri yothetsera vutoli. Nazi zomwe tikuwona pa skrini:

Monga mukuwonera, pulogalamuyo ikuwonetsa kuti idawonjezera 4 mbali zonse ziwiri za equation, kenako idatenga masikweya, ndikutenga kuphatikiza ndi kuchotsera? ndi kulemba mayankho. Kodi ndikokwanira kukopera chilichonse mu notepad? ndipo homework yachitika.

Tsopano tiyerekeze kuti tikufuna graph ya ntchito

y = x ndi²-4

Timachita izi: sinthani mawonekedwe a skrini kukhala "Graph". Zenera lolowera equation lidzawoneka; Titha kuyika ma equation angapo amodzi ndi amodzi kuti tiwone momwe akugwirizanirana wina ndi mnzake. Poyamba, minda yokhayo yolowera awiri ndi yomwe ikuwonetsedwa, koma tidzalowa m'munda umodzi wokha. Kodi tingagwiritse ntchito kiyibodi, kapena? ngati kale? kuchokera pa remote control. Kenako dinani "Graph" batani. ? ndipo graph idzawonekera, monga mu chithunzi chojambulidwa.

Ndizofunikira kudziwa kuti mutasankha zenera lazithunzi, riboni ya menyu idzasintha ndipo titha kupanga masanjidwe osiyanasiyana a tchati. Kotero ife tikhoza kuyang'ana mkati kapena kunja, kubisa nkhwangwa, kubisa malire akunja, kubisa gululi. Titha kudziwanso kusiyanasiyana kwa magawo omwe akuwonetsedwa ndikusunga chithunzi chotsatira ngati chithunzi mumitundu ingapo yodziwika bwino. Pansi pomwe pawindo la Equations and Functions? palinso njira yosangalatsa yowonetsera zowongolera zamakanema a "Graph Controls" tchati; Ndikukulangizani kuti muwone zotsatira za ntchito yawo.

Zina za pulogalamuyi? ulendo wina.
