Решите уравнение: 6sin (2x-п/6) cos (3x+п/3) - 3sin (5x+п/6) и sin (3 п/2-х) cos4x = корень3/4 - 1/2cos3x

6*sin (2*x-пи/6) * cos (3*x+пи/3) - 3*sin (5*x+пи/6) - (27^ (1/2) * sin (5*x) + 3*cos (5*x) + (9*sin (2*x) - 27^ (1/2) * cos (2*x)) * sin (3*x) + (3*cos (2*x) - 27^ (1/2) * sin (2*x)) * cos (3*x)) / 2 - 3*cos (x)
