Solve.
cos[π/6(3x - 1) ] = 1/2 for 0 ≤ x < 2π
The answer key said that the period is 4, and the answers are 1, 5, 11/3,
I do not know why the period is 4 because I thought the period is 2π/(π/6) and the solutions does not make sense to me either since they exceed the domain
Best explanation will get 10 points
