Izibalo zeMicrosoft? ithuluzi elihle lomfundi (3)

26.05.2022 /

Siyaqhubeka nokufunda indlela yokusebenzisa okuhle kakhulu (Ngiyakukhumbuza: mahhala kunguqulo 4) Uhlelo lwe-Microsoft Mathematics. Savumelana ngokumbiza ngo-MM ngamafuphi. Isici esithakazelisayo kakhulu se-MM yikhono lokupheka? izithombe ezinyakazayo futhi? amagrafu angaphezulu noma ngamanye amagama? amagrafu wemisebenzi yezinguquko ezimbili. Sizoqale sifunde ukuthi singakwenza kanjani lokhu sisebenzisa izixhumanisi ezijwayelekile zeCartesian, futhi siqale ngokudweba isithombe esimele indawo yezine kuphela? ake sithi amaphuzu. Siqhubeka ngendlela elandelayo: Chofoza ithebhu yokuthwebula. Sinweba inketho ethi "Amasethi Wedatha". Khetha i-3D ohlwini lobukhulu. Kusuka ohlwini lwezixhumanisi, khetha i-Cartesian. Chofoza inkinobho ethi Faka Isethi Yedatha. Ebhokisini lebhokisi elithi "Namathisela Isethi Yedatha", sinamathisela izixhumanisi ezintathu ezihambisanayo zeCartesian zamaphuzu ethu amane. Chofoza Igrafu. Qaphela ukuthi inombolo? faka ngokumane uthayiphe izinhlamvu ezimbili kukhibhodi: pi.

Naka izimpawu ezisefasiteleni elingenhla. Izikaki? njengoba ubona ? Ama-MM asetshenziswa kokubili ukumisa isethi (kulokhu: isethi yamaphuzu amathathu esikhaleni esinezinhlangothi ezintathu), kanye nokuqoka iphuzu ngokubhala izixhumanisi zalo. Njengoba i-MM kuwuhlelo lwaseMelika, izinombolo eziphelele nazo zihlukaniswa nezinombolo eziyingxenye hhayi ngokhefana, njengoba senza ePoland, kodwa ngechashazi.

Ngokusebenza nohlelo, ake sizame ukubamba igrafu ewumphumela ngegundane (chofoza kuyo bese ucindezela inkinobho yegundane kwesokunxele) bese uhambisa "Igundane" lethu; sizobona ukuthi igrafu ingashintshwa. Uma siyisetha ku-engeli ekhethiwe, ngenketho ethi "Londoloza igrafu njengesithombe" singayigcina njengesithombe se-png.

Qaphela futhi ukuthi ibha yamathuluzi eboniswe esithombeni esinamathiselwe iqukethe imiyalo yokufometha kweshadi. Ikakhulukazi, ungakwazi ukufihla izimbazo zokuxhumanisa kanye nohlaka lapho igrafu yonke ibekwe khona. Isikhathi sokuhlela indawo. Nansi incwadi yomuthi egunyazwe udokotela:

  • Chofoza ithebhu yeGrafu.
  • Nweba Izibalo kanye Nemisebenzi.
  • Khetha i-3D ohlwini lobukhulu.
  • Chofoza iphaneli yokuqala evelayo.
  • Ewindini lokufaka elivelayo, faka umsebenzi ofanelekile (lokhu kungenziwa kusetshenziswa ikhibhodi noma kusetshenziswa igundane nesilawuli kude ngakwesokunxele)
  • Chofoza Igrafu.

Umsebenzi ongacacile uyabonakala efasiteleni eliphezulu.

Ngokwemvelo, manje singakwazi ukushintshanisa ngokukhululekile igrafu ngegundane, sifihle amafreyimu kanye nesistimu yokuxhumanisa, njll. Futhi kuzokwenzekani uma kungekho -1, kodwa enye ipharamitha ngakwesokudla kwe-equation? Ngokwesibonelo? Ake sizame (manje sizobonisa ingxenye kuphela yefasitela elisebenzayo ukuze licace kakhudlwana):

Qaphela ukuthi iphaneli Yokulawula Ishadi manje (ngokuzenzakalelayo) isivela nenketho ye-Animation. Ngezansi sinepharamitha (kulokhu a, okungamangazi, ngoba siyibiza kanjalo thina?), Esingakwazi ukuyishintsha ngesilayidi bese sibheka umphumela. Ngokucindezela i-?Tape? eduze kwesilayidi kuzoqala ukugqwayiza njengemuvi.

Asikho isizathu sokungabuki izindawo ezimbili noma ngaphezulu zihlangana ndawonye. Ukuze wenze lokhu, efasiteleni le-Graphing, mane ungeze elinye iwindi lokuhlela umsebenzi, faka i-equation efanele bese uchofoza umyalo weGrafu. Esibonelweni sethu, sengeze isibalo nepharamitha

ukuthola (ngemuva kokwenza ukuzungezisa okufanele nokushintsha isibonisi usebenzisa inkinobho ye-Colour Surface / Wireframe kubha yamathuluzi) into efana nale:

Njengoba ubona, izilawuli zokugqwayiza manje seziyatholakala. Impela, umsebenzi wokuzungezisa ishadi ngegundane usebenza ngaso sonke isikhathi. U-MM uphatha kalula noma yini engaphezu kwe-Cartesian? Ayinandaba? ukudidiyela izinhlelo. Futhi sinezinhlelo zokuxhumanisa eziyindilinga neziyisilinda. Khumbula ukuthi indawo ekuzixhumanisi eziyindilinga ichazwa yi-equation yohlobo

okungukuthi, lokho okubizwa ngokuthi irediyasi eholayo r kuvezwa kuleli cala njengomsebenzi wama-engeli amabili; uma sifuna ukusebenzisa ama-cylindrical coordinates, kufanele sisebenzise i-equation ehlobene nokuguquguquka kwe-Cartesian neziguquguquko ze-ri?

Isibonelo, ake sibheke isithombe somsebenzi z = Kulungile? bese ungabuyeli esihlokweni samagrafu wemisebenzi nezindawo? Ake sithi futhi endabeni yezinhlangothi ezimbili esinakho hhayi kuphela uhlelo lweCartesian, kodwa futhi ne-polar, olufaneleka kahle ukukhombisa zonke izinhlobo ze-spirals eyisicaba.
