Umsebenzi weModyuli yezibalo () kwiPython sisixhobo esinamandla esikuvumela ukuba uguqule iiradians kwiidigri ngokukhawuleza nangokuchanekileyo. Isidingo sokuguqula phakathi kwezi yunithi zimbini siqhelekile kwiinkalo ezahlukeneyo, kubandakanya imathematika, i-physics, kunye nobunjineli. Kweli nqaku, siza kuntywila nzulu kwiidigri () umsebenzi, iimeko zokusetyenziswa kwayo, kunye nendlela esebenza ngayo. Kwakhona siya kubonelela ngomzekelo wenyathelo ngalinye wokuphunyezwa kwayo kwikhowudi kwaye sixoxe ngeminye imisebenzi enxulumeneyo kunye namathala eencwadi anokukunceda kwiinzame zakho zemathematika.
intshayelelo
Ukuguqula phakathi kweeradians kunye nezidanga yinxalenye ebalulekileyo yemathematika esisiseko kunye nephambili. Iiradians kunye nezidanga ziiyunithi zomlinganiselo wee-engile, kwaye zisetyenziselwa ukuchaza ubukhulu bokujikeleza kwesangqa. Ngelixa izidanga zaziwa ngokubanzi kwaye ziqondwa, iiradians zibonelela ngendlela efanelekileyo ngokwemathematika yokumela iiengile kwaye zenze izibalo zibe lula kwaye ziqonde ngakumbi.
Imodyuli yeMathematika yePython iqulethe i-built-in izidanga () umsebenzi ongathatha i-engile kwiiradians njengegalelo kwaye ibuyisele ixabiso layo elihambelanayo kwiidigri. Lo msebenzi wenza lula inkqubo yokuguqula i-engile kubadwelisi benkqubo kwaye isuse izibalo zemanuwali ezidinayo.
Ukuphumeza iidigri () Umsebenzi
Ukusebenzisa idigri () umsebenzi kwiPython, kufuneka ungenise ngaphandle i izibalo imodyuli kuqala. Nje ukuba umnqongo uthathwe ngaphandle, unofikelelo kwizidanga () umsebenzi kunye nayo yonke eminye imisebenzi yezibalo equlethwe kumnqongo womlinganiselo. Nantsi indlela onokusebenzisa ngayo izidanga () umsebenzi:
import math radians = 1.57 degrees = math.degrees(radians) print(degrees)
Kulo mzekelo, sithatha ngaphandle imodyuli yezibalo kwaye sinike i-engile kwiiradians (1.57) kuguquguquko 'lweradians.' Emva koko sisebenzisa i izidanga () umsebenzi ukuguqula i-engile kwiidigri kwaye ugcine isiphumo kuguqulo 'lwezidanga.' Ekugqibeleni, siprinta umphumo.
Ukuqonda iKhowudi
Masingene nzulu kwinyathelo ngalinye ukuze siqiniseke ukuba siyiqonda ngokupheleleyo indlela ikhowudi esebenza ngayo.
1. Thatha ngaphandle imodyuli yemathematika: Ngokurhweba ngaphandle umnqongo wezibalo, sifumana ufikelelo kwiidigri () umsebenzi ukongeza kwimisebenzi emininzi yezibalo.
import math
2. Yabela i-engile kwiiradians: Sigcina i-engile kwiiradians (1.57) kuguquguquko “lweradians.”
radians = 1.57
3. Sebenzisa izidanga () umsebenzi: Sisebenzisa idigri () umsebenzi ukuguqula i-engile kwiiradians ukuya kwidigri kwaye sigcine isiphumo kuguquguquko "iidigri."
degrees = math.degrees(radians)
4. Shicilela iziphumo: Siprinta i-angle eguqulwayo kwiidigri (89.954 degrees).
print(degrees)
Imisebenzi eNxulumeneyo kunye namaThala eencwadi
IModyuli yeMathematika inikezela ngaphezulu kunezidanga () umsebenzi. Kukho eminye imisebenzi enxulumeneyo kunye namathala eencwadi anokukunceda wenze izibalo ezahlukeneyo zemathematika.
- math.radians(): Lo msebenzi uguqula i-engile ukusuka kwidigri ukuya kwiiradians. Luguqulo lwedigri () umsebenzi kwaye ivumela umva-na-phambili uguqulelo phakathi kweradians kunye nezidanga.
- math.sin(), math.cos(), math.tan(): Le misebenzi yetrigonometric ithatha ii-engile kwiiradians njengegalelo kwaye ibuyisele i-sine, i-cosine, kunye ne-tangent ye-engile, ngokulandelelanayo. Zinokudityaniswa kunye nezidanga () kunye neradians () imisebenzi xa kufuneka.
- numpy: Ithala leencwadi elidumileyo lokubalwa kwamanani ePython, inumpy ibonelela ngemisebenzi eyahlukeneyo yezibalo kunye noluhlu lwedatha olululo eyenza lula ukuphunyezwa kwemisebenzi yezibalo entsonkothileyo.
Ukuqukumbela, umsebenzi weModyuli yeMathematika kwiPython uxabiseke kakhulu ekuguquleni iiradians ukuya kwizidanga. Kuchanekile ukuphumeza kwaye kuluncedo kakhulu kwizicelo ezahlukeneyo zemathematika. Imisebenzi eyeleleneyo njenge math.radians() kunye neelayibrari ezifana nenumpy ziphucula ngakumbi ukukwazi kwakho ukwenza imisebenzi yemathematika kwiPython.
