Microsoft math? chishandiso chikuru chemudzidzi (2)
Isu tinoenderera mberi nekudzidza mashandisiro akanakisa (Ndinokuyeuchidza: yemahara kubva kuvhezheni 4) Microsoft Mathematics chirongwa. Isu tinobvumirana kuti muchidimbu tichaidaidza kuti MM.
Very interesting? uye vakasununguka? basa repurogiramu ndiko kukwanisa kushandisa mamwe "akagadzirira-akagadzirwa" avo. Mu "Formulas uye Equations" tab? pane rondedzero yemafomula nemaequation ayo mwana wechikoro aimbofanira kuziva nemusoro. Uye nhasi aya ndiwo mabatanidzwa akakodzera kuziva, asi kana uchishandisa MM hazvidi kudzimwa kubva mundangariro (izvo zvinogona kukonzera kukanganisa, semuenzaniso, semhedzisiro yekudzvanya kiyi isiriyo). Tose takagadzirira. Paunodzvanya pane yakatsanangurwa tab, runyorwa rwemafomula runovhurwa, rwakakamurwa kuita mapoka: Algebra, Geometry, Trigonometry, Fizikisi, Chemistry, Mitemo yevanotsanangura, Properties of logarithms uye Constant (Algebra, Geometry, Fizikisi, Chemistry, Exponential mutemo, Properties of logarithms). uye zvisingaperi). Semuenzaniso, ngativhurei boka reAlgebra. Tichaona mamwe maitiro; sarudza yekutanga, iyi ndiyo nzira yemidzi ye quadratic equation. Heino formula:
Kudzvanya pairi (kana chero imwe) nebhatani rekurudyi rembeva kunovhura diki diki menyu; ine mirairo imwe, miviri kana mitatu: kopi, kuvaka uye kugadzirisa. Muchiitiko chedu, pane mirairo miviri: kopi uye bhabhatidza; kukopa kunoshandiswa kusuma (uchishandisa iyo paste command, hongu) iyo yakasarudzwa template mubasa rakanyorwa. Ngatishandisei murairo wekuronga ("Build this equation?"). Heino mhedzisiro skrini (chiverengero chinogumira kuchikamu chinoshanda): Kudivi rekurudyi, isu tine girafu yequadratic equation mune yakajairika fomu, mhinduro yacho inotsanangurwa neformula yatakashandisa. Kudivi rekuruboshwe (bhokisi rakatenderedzwa mutsvuku) isu tava nemhando mbiri dzinonakidza: Trace uye Animate.
Kushandisa yekutanga kuchafambisa pfungwa yacho pagirafu rose, isu tichiri kuona? chaiwo kukosha kweanoenderana coordes. Ehe, isu tinogona kumisa yekutevera animation chero nguva. Muchikamu chechirongwa tinozoona chimwe chinhu chakadai:
Iyo Animate chishandiso chinokutendera iwe kuti uwane zvakatowanda zvinonakidza mhedzisiro. Ndapota cherechedza kuti pakutanga mune inooneka yekudonha-pasi runyorwa tine parameter seti (kunze kwevatatu muequation: a, b, c) uye padivi payo inotsvedza diki inoratidza kukosha 1. Pasina kushandura parameter kusarudzwa, bata slider necursor uye uende nayo kuruboshwe kana kurudyi; tichaona kuti girafu yequadratic equation inoshandura chimiro chayo zvichienderana nekukosha kwe. Kutanga iyo animation nebhatani rekutamba rinozivikanwa richava nemhedzisiro yakafanana, asi ikozvino komputa ichaita basa rese rekutisetera muteresi. Ehe, iyo yakatsanangurwa chishandiso chishandiso chakanakira kukurukura mafambiro ekusiyana kweiyo quadratic function. Unogona ? nokumwe kuwedzeredza? vanoti anotipa ruzivo rwese pamusoro pemakona matatu mune imwe pfupi "piritsi".
Ini ndinokoka vaverengi pachavo kuti vaedze zvakafanana kushandisa mamwe mafomula kubva muboka realgebraic formula. Izvo chete zvakakosha kucherechedza kuti muboka iri tinogona zvakare kuwana mafomula ane hukama neanalytic geometry? semuenzaniso, nekuverenga kwehumwe huwandu hwakabatana nesphere, ellipse, parabola kana hyperbola. Mamwe mafomula ane hukama nejometry anofanirwa kuwanikwa muboka reGeometry; nei vanyori vechirongwa vakaisa chikamu pano uye chikamu ipapo? chakavanzika chavo chinotapira?
Maformula mufizikisi uye chemistry anobatsirawo zvakanyanya, achikubvumidza kuti uite maverengero akasiyana ane chekuita nesainzi idzi uchibatsirwa neMM. Pane munhu ane laptop kana netbook rinobatsira sei (uye kudzidzisa nemudzidzisi asina kujairika?)? nechirongwa cheMM chakatakurwa pachigadzirwa ichi, haafanire kutya chero bvunzo kubva kusainzi chaiyo? Zvakanaka, zvakadini nebasa rechikoro? mufaro pachawo.
Ngatiendei kune chinotevera chishandiso, chinongoshandiswa kudzidza matatu matatu. Ndizvozvo pano: Mushure mekudzvanya munzvimbo yakaratidzwa, hwindo rakaparadzana reTriangle Solver rinovhura:
Panzvimbo yakanyorwa nemuseve mutsvuku, tine bhokisi rekudonha rine sarudzo nhatu dzekusarudza kubva; isu tinogara tichitanga kubva kune yekutanga, tichipinda zvitatu zvezvitanhatu zvakakosha mundima dzinoenderana (mativi a, b, c kana makona A, B, C?, nekusarudzika muchiyero cheradial). Mushure mekupinda iyi data, isu tichaona kudhirowa kwetatu rinoenderana kumusoro kana tikasarudza hunhu husingaenderane nechero katatu iripo? yambiro yekukanganisa ichaonekwa.
Tichishandisa rondedzero yekudonhedza-pasi yataurwa munzvimbo ino, tichaona (mune yechipiri sarudzo) ndeapi matatu matatu atakavaka - rectangular, angular, nezvimwewo? kubva kune chechitatu tinowana nhamba yedata pamusoro pehurefu huri mune iyi katatu uye panzvimbo yayo.
Yekupedzisira tebhu inowanikwa paRibhoni reKumba ndeye Unit Converter, i.e. unit uye chiyero chekushandura.
Inopa chishandiso chinotevera:
Kushanda nechishandiso ichi chiri nyore kwazvo. Kutanga, kubva kumusoro-pasi menyu, sarudza rudzi rweyuniti (pano Urefu, kureva kureba), zvino muzasi-pasi minda inoisa mazita emayuniti kuti ashandurwe? toti tsoka nemasentimita? Pakupedzisira, mu "Input" hwindo, tinoisa kukosha kwakakosha, uye mu "Output" hwindo, mushure mekudhinda "calculate" bhatani, tinowana chibereko chaidiwa. Trite, asi inobatsira zvikuru, kunyanya mufizikisi. Next ? iine zvishoma zvepamberi MM kugona.
