Вроде так)

1. arcsin(1/2) + arccos(1/2) = π/6 + π/3 = π/2.

2. arcsin(1) + arccos(1/2) + arcsin(√3/2) = π/2 + π/3 + π/6 = 2π/3.

3. arctan(1) + arctan(1) + arccos(√2/2) = π/4 + π/4 + π/4 = 3π/4.

4. arctan(√3) - arccot(0) - arccos(1/2) = π/3 - (π/2) - π/3 = -π/2.

5. arcsin(-1) - arccos(-1/2) = -π/2 - (2π/3) = -π.

6. arctan(√3/3) + arctan(-√3) - arcsin(-1) + arccos(-√2/2) = (π/6) - (π/3) - (-π/2) + π/4 = π/4.
