Misalkan cos x = p, maka persamaan nya menjadi
2p2 + p - 1 = 0

(2p-1)(p+1) = 0

p = 1/2  atau p = -1

cos x = 1/2 atau cos x = -1

  1. cos x = cos 60

               x = 60 + k . 360

k = 0 >> x = 60
               x = -60 + k.360
k = 1 >> x = -60 + 360 = 300

2. cos x = cos 180

                 x = 180 + k . 360

k = 0 >> x = 180
