find all solutions on 0 is greater than or equal to theta < 2pi
cos theta= 2sqrt3/3
41/2sin theta= (16+sqrt3)/4
3(sqrt3)= 3cot theta
2=12sin theta

2√3/3 = 1.15
cosθ is never greater than 1.
_____________________
If you mean 4(1/2)sinθ= (16+√3)/4
sinθ = 4  √3/4
sorry, sinθ is never greater than 1.
If you mean 4(1/2sinθ) = (16+√3)/4
sinθ = 2/(32√3) = .066
θ = 3.78°
_________________
cotθ = √3
θ = 30°
__________________
sinθ = 1/2
θ = 30°
I'll let you figure out the other angles less than 2pi
