sin(2x-3)=0,5
sin(2x-3)= 1/2
sin( π- (2x-3)) = 1/2
2х - 3 = arcsin (1/2)
sin (π - 2x + 3 ) = 1/2
2x-3 = π/6
π - 2x+3 = arcsin (1/2)
2x-3 = π/6+ 2k π
π - 2x + 3 = π/6
x= π/12 + 3/2 + kπ
π - 2x + = π/6 + 2k π
x = π/12 + 3/2 + kπ
x= 5π/12 + 3/2 - kπ
x= 5π/12 + 3/2 + kπ
x= 5π/12 + 3/2 + kπ
x = π/12 + 3/2 + kπ
x= 5π/12 + 3/2 + kπ
