find all solutions on 0 is greater than or equal to theta < 2pi

cos theta= 2sqrt3/3
4-1/2sin theta= (-16+sqrt3)/4
3(sqrt3)= -3cot theta
-2=-1-2sin theta

  • math - ,

    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

    yeah im lost i have no idea what i did
