1. express the following equations for value of theta in the interval 0< theta < 2pie, give your answer in terms of pie

cosec1/2theta = 2 square root of 3 all over 3

express the following equations for value of theta in the interval 0< theta < 2pie, give your answer in terms of pie

cosec1/2theta = 2 square root of 3 all over 3
cosec1/2x=(2√3)/3
sin1/2x=3/(2√3)
1/2x=60°=π/3
x=120°=2π/3

3. n=0 is the only one which gives the required range of x. Therefore
