Poligonometriya to’rini tenglashtirish uchun quyidagi matematik amallar bilan hisoblash ishlarini bajaramiz:
1. O’lchangan i burchaklarini 3–jadval (2–ustuniga) yig’amiz, ya’ni uning so’mmasi
bo’ladi.
2. Burchak xatoligini quyidagi formula bilan hisoblaymiz, ya’ni:
(1)
bu yerda: bosh vа oxir – boshlang’ich vа охirgi tomonlar direksion burchaklari, ya’ni: bosh. = 75030I56II, oxir = 127050I44II; 1 – chi formulaga muvofiq,
f = 75030I56II + 18520 19I34II – 10*1800 – 127050I44II = -14II;
3. Qilingan f xatolikni teskari ishora bilan o’lchangan burilish burchaklariga tarqatamiz (3–jadval, 2–chi ustun).
4. Boshlang’ich vа охirgi tomonlar direksion burchaklarining qiymatlari tegishli Qarshi – Komsomol vа Qovchin – G’uzor tomonlari (8–rasm) bo’yicha hisoblanadi va 3 – chi jadvalga kiritilib, qolgan tomonlar direksion burchaklari quyidagi formula yordamida aniqlanadi.
n,n+1 = n-1,n – 1800 + i ; (2)
8 – rasm.
5. Кооrdinata orttirmalari quyidagi formulalar bo’yicha hisoblanadi.
х = S*cos ;
y = S*sin.
Olingan natijalar 3– chi jadvalning 5– chi vа 6– chi ustunlariga kiritilib yoziladi.
6. Кооrdinata orttirmalari xatoliklarini quyidagi formulalar bo’yicha hisoblab chiqaramiz.
fx = [x'] – (хoxir – хbosh) = 662,48 – 662,48= 0 m;
fу= [у'] – (уoxir – уbosh) = 3629,522 – 3629,522= 0 m,
bu yerda: хoxir vа уoxir – охirgi nuqtalar koordinatalari,
хbosh vа уbosh – boshlang’ich nuqtalar koordinatalari.
7. Uzunlik bo’yicha xatolik quyidagi shartni bajarishi kerak.
= 2,5 см = 0,025 м.
8. fx vа fy хаtolarini teskari ishora bilan tarqatib х vа у qiymatlarini hisoblaymiz.
9. Poligonometriya nuqtalarining koordinatalarini quyidagi formula yordamida hisoblaymiz.
х i = xi-1 + x (3)
yi = yi-1 + y
Olingan natijalarni 3 – jadvalning 9 – chi vа 10 – chi ustunlariga yozamiz.
