Объяснение:
1) sin(3-2x)= - 1/2
sin ( π- ( 3-2x)) = - 1/2
3-2x =.arcsin( - 1/2)
sin (π-3 + 2x ) = -1/2
3-2x = - π/6
π - 3 + 2x = arcsin ( - 1/2 )
x = π/12 + 3/2 - kπ , k ∈ Z
π - 3 + 2x = - π/6 + 2kπ , k ∈ Z
x=π/12 + 3/2 + kπ , k ∈ Z
x= - 7π/12 + 3/2 + kπ ,k ∈ Z
x= 3/2 + π/12 + kπ ,k ∈ Z
x= 3/2 + 5π/12 + kπ ,k ∈ Z
