2sin (x)cos (x) - sin (x) = 0. Factoring out sin (x): sin (x) (2cos (x) - 1) = 0. Using the Zero Product property: sin (x) = 0 or 2cos (x) - 1 = 0. Solving the second equation for cos (x) we get: sin (x) = 0 or cos (x) = 1/2. So our solutions are all the angles whose sin is 0 or all the angles whose cos is 1/2.
