For each problem, determine the values of x such that 0 ≤ x < 2π that satisfy equation.
(1) Solve sin x cos x = 0. (Answers: x = 0, π/2, π, 3π/2)
(2) Solve 2 sin2 x − sin x − 1 = 0. (Answers: x = π/2, 7π/6, 11π/6)
(3) Solve cos x + cos 2x = 0. (Answers: x =π/3, π, 5π/3)
(4) Solve 2 cos x + sec x = 3. (Answers: x = 0, π/3, 5π/3)
(5) Solve sec x − 1 = tan x. (Answer: x = 0)
