Реебят,, решить, надо) sin^2(3x-пи/8)=1/2

1)sin(3x-пи/8)=1/2                                           и              2)sin(3x-пи/8)= - 1/2

3х - pi/8 = (-1)^n (pi/6) +pin                                                3х - pi/8 = (-1)^(n+1) (pi/6) +pin  

3x = (-1)^n (pi/6) +pi/6+pin                                                  3x = (-1)^(n+1) (pi/6) +pi/6+pin   

x = (-1)^n (pi/18) +pi/18+pin /3                                             x = (-1)^(n+1) (pi/18) +pi/18+pin /3
