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)

the interval is 0( which is less than or equal to) theta ( which is less than) 2pi

-2cos(x) = 1
cos(x) = -1/2
the related angle is cos inverse of 1/2 , which is 60 degrees

cos is negative in the 2 and 3 quadrants
