Microsoft Mathematics chishandiso chikuru kumudzidzi (1)

Kambani yeBill Gates (kunyangwe atova "munhu ari oga", asi mushure mezvose ndeye "chiso" chisingadzimiki) munguva pfupi yapfuura yakatumira paInternet chishandiso chikuru chemhando iyi, iyo masayendisiti ekombuta anodana CAS (Computer Algebra System? Computer Algebra System) ) ) Kune maturusi akawanda ane simba kunze uko, asi ichi chinoita sechinonyatsoenderana nezvinodiwa nemudzidzi here? uye kunyangwe mudzidzi weyunivhesiti yehunyanzvi. MM inogona kugadzirisa chero equation, mabasa ekuronga eimwe kana maviri akasiyana, kusiyanisa uye kubatanidza, uye ane humwe hunyanzvi, hwatichataura nezvazvo gare gare.

Inoita zviverengero zvese nenhamba (panhamba chaidzo uye dzakaoma) uye nenzira yekufananidzira, ichishandura mafomula zvichienderana. Izvo zvakakosha kuti hazviuye pasi pakuburitsa mhedzisiro, asi inomiririra kuverenga kwepakati nezvikonzero; izvi zvinoreva kuti yakanakira kubata marudzi ese emabasa epamba. Chete chinogumira ndechekuti unofanirwa kuziva Chirungu. Zvakanaka, eh? Chirungu chinongova mazana mashoma mazwi?

Chirongwa ichi chinodaidzwa kuti Microsoft Mathematics, yaimboita madhora makumi maviri, sezvo yechina vhezheni yakasununguka zvachose. Pane . Nekudaro, usati waita izvi, ita shuwa kuti komputa yako inosangana nezvinodiwa; uye ndeaya anotevera: sisitimu yekushandisa kanenge Windows XP ine Service Pack 20 (zvechokwadi, inogona kuva Vista kana Windows 3), Microsoft .NET Framework 7 SP3.5 yakaiswa, processor ine wachi kumhanya kwe1 MHz (zvishoma) kana 500. GHz (inokurudzirwa), 1 MB shoma RAM (256 MB kana kupfuura inokurudzirwa), vhidhiyo kadhi ine inokwana 500 MB yemukati ndangariro, ingangoita 64 MB yemahara disk nzvimbo.

Izvi hazvisi kunyanya zvakakura zvinodiwa, saka mushure mekurodha faira yekuisa kubva kukero yakapihwa, tinoenderera kune yekumisikidza banal uye mhanyisa chirongwa.

Iwindo rebasa rinotevera richaonekwa:

Zvinonyanya kukosha kurudyi: kune mahwindo maviri anozove asina kana iwe uchivhura chirongwa. Pazasi chaipo (chena, nhete, ine tsamba? Uye?) Pane hwindo reruzivo, chaizvoizvo risingakoshi, kunyange zvazvo mukufamba kwekuverenga rine tsanangudzo uye mazano; Chepiri? fomula yekupinza hwindo, tinogona kuzviita zvese kubva kukhibhodi uye kushandisa "kure"? nemabhatani; muchiitiko chekusarudza chishandiso chekupedzisira kushanda nechirongwa, iwe unongoda mbeva. Calculation result? unoreva mafomula akashandurwa kana girafu rinoenderana? vanoonekwa muhwindo rechipiri renzvimbo yekushanda, pakutanga grey, ine zita rokuti "Worksheet"; Zvakakosha kuziva kuti padivi petabhu ine chinyorwa ichi pane "Chati" tab, yatichashandisa. zviri nyore sei kufungidzira? patinenge tichida kudzidza magirafu ekushanda.

Paunenge uchitanga kudzidza chirongwa chechirongwa, iwe unofanirwa kuterera kune matatu minda inoratidzwa nemiseve mumufananidzo wakabatanidzwa. Iri ndiro bhatani rekusarudza nzvimbo yekuverenga ("Chaiyo" yenhamba chaidzo kana "Complex" yenhamba dzakaoma); hwindo "Decimal nzvimbo", kureva, kuisa kururamisa kwekuverenga (nhamba yenzvimbo dzedesimali; zviri nani kusiya "Isina kugadzika" - ipapo komputa ichasarudza iyo yakarurama pachayo); Pakupedzisira, bhatani reEquation Solver, kana radzvanywa, komputa inoongorora mafomula akaiswa uye, pamwe, kugadzirisa iwo equations. Mabhatani asara anofanirwa kusiiwa asina kuchinjika izvozvi (rimwe rawo, rakanyorwa kuti "Ink", rinongobatsira pamidziyo yekubata-bata).

Inguva yekuita masvomhu ekutanga.

Ngatigadzirise quadratic equation

x²-4=0

Nzira 1 yekupinda basa: Isa cursor mubhokisi rekuisa fomula wodzvanya makiyi x, ^, -, 4, =, 0 munhevedzano.Ziva kuti pakushandisa ^ chiratidzo sechiratidzo cheexponentiation, museve unoenda kumusoro uchashandiswa.

Nzira 2 yekupinda basa: paremote control? kuruboshwe tinodzvanya shanduko x, chiratidzo cheexponentiation ^ uye mamwe makiyi anoenderana.

Muzviitiko zvese izvi, hongu, equation yedu ichaonekwa mufafitera rekuisa fomula. Zvino dzvanya Enter kiyi. kurudyi kwenzvimbo yekupinda? uye muhwindo remhedzisiro kumusoro kune rekodhi nezve basa iri mumutauro wechirongwa:

Solvex²-4=0,x

zvinoreva kuti "gadzirisa equation mumaparentheses neruremekedzo"), uye pazasi pane mitsetse mitatu ine blue pluses yakanyorwa se "matanho ekugadzirisa". Izvi zvinoreva kuti purogiramu yakawana nzira nhatu dzekugadzirisa dambudziko uye inotisiya nechisarudzo chatinoda kuratidza (isu tinogona, zvechokwadi, kuvaona vose). Purogiramu iri pasi apa inonyora zvinhu zviviri.

Semuenzaniso, ngatitange nzira yechipiri yekugadzirisa. Hezvino izvo zvatichaona pane iyo skrini:

Sezvauri kuona, chirongwa ichi chinotaridza kuti chakawedzera mana kumativi ese equation, ndokutora sikweya midzi, ndokuitora nekuwedzera uye kubvisa? uye akanyora pasi mhinduro. Zvakakwana here kukopa zvese munotepad? uye basa remumba rinoitwa.

Zvino ngatiti isu tinoda girafu rekuita

iwe = h²-4

Isu tinoita izvi: shandura iyo skrini ku "Grafu". Hwindo rekupinda equation richaonekwa; tinokwanisa kuisa maequation akati wandei one by one kuti tione kuti anodyidzana sei. Pakutanga, minda chete yekupinda mairi inoratidzwa, asi isu tichangopinda imwe chete mumunda une shaded. Tinogona kushandisa kiibhodhi, kana? like before ? kubva kureutu. Wobva wadzvanya bhatani re "Grafu". ? uye girafu ichaonekwa, sezviri mumufananidzo wakabatanidzwa.

Izvo zvakakosha kucherechedza kuti mushure mekusarudza iyo giraidhi hwindo, iyo menyu ribhoni ichachinja uye isu tichakwanisa kuita akasiyana fomati yechati. Saka isu tinokwanisa kuswededza mukati kana kunze, kuvanza matemo, kuvanza muganho wekunze, kuvanza grid. Isu tinokwanisa zvakare kuona huwandu hwekusiyana kweiyo inoratidzwa paramita uye chengetedza inozobuda girafu semufananidzo mune akati wandei anonyanya kufarirwa graphic mafomati. Pazasi chaipo peEquations uye Mabasa hwindo? kune zvakare inonakidza sarudzo yekuratidza iwo animation control ye "Graph Controls" chati; Ndinokupa zano kuti utarise maitiro ekushandisa kwavo.
