a) arcSin(-1/2) = -π/6
     arcCos√3/2 = π/3
<
б) arctg√3 = π/3
     arctg1 = π/4
>
в)arcCos1/2 = π/3
    arctg(-1) = -π/4
>
г) arcCtg√3/3= π/6
    arctg1 = π/4
<

Answer 2

arcCos√3/2 = π/6

Answer 3

а) arcsin(-1/2) = -π/6 <  π/6 =arccos√3/2 .
б) arctq√3 =π/3 > π/4 =arctq1 .
в) arccos(1/2) =π/3 > -π/4 =arctq(-1).
г) arctq√3/3 =π/6 <  π/4 =arctq1.
