[ 1/1Inequality]
    Assignment:Find the solution set of inequality [π×（x+1）]/6×sin((x*π)/6)-π*x/6×sin(((x+1)*π)/6) <0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( π × ( x + 1 ) ) / 6 × sin ( ( x * π ) / 6 ) - π * x / 6 × sin ( ( ( x + 1 ) * π ) / 6 ) <0         (1)

---

    From inequality(1)：
         -21.329358 < x < -15.259818 或  -9.091535 < x < -1 或  -1/2 < x < 0 或  8.091535 < x < 14.259818 或  20.329358 < x < 26.367568

---

    The final solution set is :
         -21.329358 < x < -15.259818 或  -9.091535 < x < -1 或  -1/2 < x < 0 或  8.091535 < x < 14.259818 或  20.329358 < x < 26.367568
