Пошаговое объяснение:

№2 . 1) arcsin(- √2/2) + 3π/4= - arcsin(√2/2)+ 3π/4 = - π/4 +3π/4 = 2π/4=π/2;

2) arccos1/2 - π/6 = π/3 - π/6 = π/6 ;

3) arctg1/√3 + 5π/6 = π/6 + 5π/6 = 6π/6 = π ;

4) 4arcctg√3 - 2π/3 = 4* π/6 - 2π/3 = 0 ;

5)  arctg(- √3 ) + 4π/3 = - arctg√3 + 4π/3 = - π/3 + 4π/3 = 3π/3 = π ;

6) arcsin(- 1 ) + π/2 = - arcsin 1 + π/2 = - π/2 + π/2 = 0 ;

7) arccos( - √3/2 ) + 7π/6 = π - arccos( √3/2 ) + 7π/6 = π - π/6 + 7π/6 =

    = 5π/6 + 7π/6 = 12π/6 = 2π ;

8) arcctg(- 1 ) + π/4 = π - arcctg1 + π/4 = π - π/4 + π/4 = π .
