6-89.
  1. Solve for x on the indicated domain. Homework Help ✎

    1. cos x = 0, [0, 2π]

    2. 2 sin x + square root of 2 = 0, [0, 2π]

    3. cos x(2 sin x + square root of 2) = 0, [0, 2π]

    4. cos x(2 sin x + square root of 2) = 0

Use the Zero Product Property. Then combine parts (a) and (b).

Solve for all solutions.
Add a 2πn to each solution in [0,2π] where n is any integer.
