Question

Cosx sinx - cosx = 0

Answer 1

• 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)
