Final Answer: The solutions to the equation cos(x)=32 are 2π3 and 4π3.

Steps

Step 1 :Determine the solution(s) for the following where 0πα2π : cos(x)=32

Step 2 :The cosine function is negative in the second and third quadrants. The reference angle associated with cos(x)=32 is π6 (or 30 degrees).

Step 3 :Therefore, the solutions to the equation are 2π3 and 4π3.

Step 4 :Final Answer: The solutions to the equation cos(x)=32 are 2π3 and 4π3.
