Question

Помогите!!!!!!!
Вычислите!!!!!!

Answer 1

$arccos( sqrt{3}/2)-arcsin(- sqrt{2}/2) - pi /4 \ \ = frac{ pi }{6}- (- frac{ pi }{4})- frac{ pi }{4}= frac{ pi }{6}+ frac{ pi }{4}- frac{ pi }{4}= frac{ pi }{6}$

$arcsin(- sqrt{3}/2)-arccos(- sqrt{3} /2)+2= \ \ = - frac{ pi }{3} - frac{5 pi }{6}-2= frac{-2 pi -5 pi -12}{6}=- frac{7 pi -12}{6}=- frac{7 pi }{6}-2$
