Solve this equation on the interval 0 θ < 2π. If there is only one solution, write it in the first box and write NONE in the second box. If there is no solution, write NONE in both boxes.
Round your answer(s) to two decimal places using radians.
2 cos(θ) + 1 = 2
θ = (smaller value of θ)
θ = (larger value of θ)
