Beyond the Answer

Bu ifodani hisoblashdan avval, trigonometriya qoidalarini yoki identitetsiyalarni qo'llashimiz mumkin. Misol uchun, $\sin$ va $\cos$ funksiyalari o'rtasidagi muvozanatni hisobga olgan holda, ushbu ifodani qulay shaklga keltira olamiz. Endi sizga kiritilgan ifodaning qiymatini hisoblash uchun, avval $\sin 43 \cos 17$ ni, hanuzgacha boshqa qismlar bilan qo'shgan holda hisobga olamiz. Agar biz buni dastlabki tasviyaga qo'shsak: \[ \sin 43 \cos 17 + \cos 43 + \sin 17 = \frac{1}{2}(\sin(43 + 17) + \sin(43 - 17)) + \cos 43 + \sin 17. \] Shunday qilib, har bir qismi alohida hisoblangandan so'ng, umumiy natija aniqlanadi. Zotan buni amalga oshirganingizda, siz aniq natijani olasiz! Olinadi: Natija 1.8513 atrofida. Shunday qilib, natijani kelib chiqadi.
