Answer:

  • Factor then solve.

x = π /2 +  2 π n  ,  3 π/ 2  +  2 π n , for any integer  n

(If you need to find all complex solutions that was the answer)

  • Move all terms to the left side and set equal to zero. Then set each factor equal to zero.

x  =  π /2  +  π n  , for any integer  n

(And If you need to find solve for x this was the answer)
