arcsin√3 / 2 = π / 3arccos (-√2 / 2) = 3π / 4-arctg(-1) = -π / 4arcctg(-1) = π - π / 4 = 3π / 4
Таким образом,π / 3 + 4*(3π / 4) - (-π / 4) + 3π / 4 =π / 3 + 3π + 4π + π + 3π= 9π + π / 3 = 9π + 1/3
arcsin√3 / 2 = π / 3
arccos (-√2 / 2) = 3π / 4
-arctg(-1) = -π / 4
arcctg(-1) = π - π / 4 = 3π / 4
Таким образом,
π / 3 + 4*(3π / 4) - (-π / 4) + 3π / 4 =
π / 3 + 3π + 4π + π + 3π
= 9π + π / 3 = 9π + 1/3
