WebWe can use the zero-product property, which states that if the product of two factors is equal to zero, then at least one of the factors must be equal to zero. Setting each factor to zero and solving for x separately, we get: sin x - 1/2 = 0 or 2cos x - 1 = 0 For sin x - 1/2 = 0: Adding 1/2 to both sides, we get: sin x = 1/2
