UYENZA NJANI IMISEBENZI YEGRAFU?

Ukuba ukhe wazibuza ukuba uwenza njani umsebenzi wegrafu (onezinto ezimbini ubuncinci eziguquguqukayo), uze kwinqaku elichanekileyo, kwaye yinto elula kakhulu ukuyenza kwaye apha siza kukubonisa ukuba njani.

Ukugrafa imisebenzi kunokwenzeka kwaye isixhobo esiza kwenza ngayo ezi grafu sibizwa ngokuba yinqwelomoya yeCartesian, inqwelomoya yeCartesian ayiyonto ingaphezulu komanyano lwamanani amabini.

Ukuba uyakhumbula kwamanye amanqaku esiwapapashayo, umgca-manani yindlela yokuzoba amanani kodwa oku kwenzeka kwinqwelomoya enye okanye into eguquguqukayo, ngelixa kwimisebenzi sinezinto ezimbini eziguquguqukayo (ezixhomekeke nezizimeleyo). Umanyano lwelayini zamanani ezimbini lwenziwa ngenqaku eliqhelekileyo elilinqaku u-0, umgca-manani usetyenziswa ngokuthe nkqo ukumela amaxabiso ka-X esiya kuwabiza ngokuba yi-X axis kunye nomgca manani ngokuthe tye ukumela U-Y uxabisa ukuba siya kuyibiza ngokuba yi-Y axis.

Siza kuqala sichonge ixabiso le-X ngokuhamba kwi-axis ethe tye, emva koko siya kuhamba ngokuthe nkqo de sifumane ixabiso le-Y. Inqwelomoya yeCartesian yahlulahlulwe ibe yi-quadrants evumela ukuba kube lula ukwenza igraphing.

I-quadrant yokuqala: yindawo yenqwelomoya yeCartesian apho iinguqu ezimbini zilungile
I-quadrant yesibini: Kulapho i-X iguquguqukayo i-negative kwaye i-Y iguquguqukayo.
I-quadrant yesithathu: Kulapho iinguqu ezimbini zingalunganga.
I-quadrant yesine: Kulapho i-X i-positive kwaye i-Y iguquguqukayo.

Enye into ebalulekileyo ukongeza kwesi sihloko segrafu yemisebenzi kukuba kukho indlela yokuchonga ukuba ibinzana lingumsebenzi okanye hayi, kwaye ngokumela intetho kwinqwelomoya yeCartesian, kufuneka unike amaxabiso ahlukeneyo X ukuze ukwazi ukufumana u-F(X) kwaye upeyinte amanqaku owafumanayo, uwadibanise nomgca kwaye ukuba nawaphi na amanqaku adibana nelinye inqaku kumgca othe nkqo (amaxabiso e-F(X)) ithetha ukuba ayingomsebenzi.

Khumbula ukuqhubeka nokuphanda ngayo yonke into esikufundisa yona ukuze siqhubeke sikhula kunye kwaye senze imithambo emininzi ukuze usifunde kakuhle isifundo. Nzakubona!
