2arcsin(-√2/2) = -π/83arccos(-√3/2) = -π/6arctg(-1) = -π/42arccos(0) = π/2
Putting it all together:-π/8 - π/6 - π/4 - π/2 = -2π/8 - 3π/6 - 4π/4 - 8π/8 = -17π/8
Therefore, the answer is -17π/8
2arcsin(-√2/2) = -π/8
3arccos(-√3/2) = -π/6
arctg(-1) = -π/4
2arccos(0) = π/2
Putting it all together:
-π/8 - π/6 - π/4 - π/2 = -2π/8 - 3π/6 - 4π/4 - 8π/8 = -17π/8
Therefore, the answer is -17π/8
