    Trigonometric function

    I need to find the value of the trigonometric function y=(1/2)sin(2x-2π), x's range is (π/3 ; 5π/8), i am okay with the first few steps :
    π/3 < x < 5π/8 |*2
    2π/3 < 2x < 5π/4 | - 2π
    -4π/3 < 2x - 2π < - 3π/4
    However, here's when i get confused
    How should i solve the rest of the problem?
