Find all solutions of the trigonometric equation in terms of integer k and the solutions in a single period [0, 27). Express your answer in radians. 2 cos (t) = 1 (Give your answer in the form of a comma-separated list if needed. Express numbers in exact form. Use symbolic notation and fractions where needed. Use k to represent any integer.) This is asking you to find all solutions, so first find 2 solutions between 0 and 2л, then add whole circles, +2лk =
