    Assignment:Find the solution set of inequality 0.25*(sin(x/2)^2)+9/64*(sin(x/2)^4) <0.005 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        0.25 * ( sin ( x / 2 ) ^ 2 ) + 9 / 64 * ( sin ( x / 2 ) ^ 4 ) <0.005         (1)

---

    From inequality(1)：
         -12.848588 < x < -12.284153 或  -√43104519/1000 < x < -6.000967 或  -0.282218 < x < 0.282218 或  6.000967 < x < √43104519/1000 或  12.284153 < x < 12.848588

---

    The final solution set is :
         -12.848588 < x < -12.284153 或  -√43104519/1000 < x < -6.000967 或  -0.282218 < x < 0.282218 或  6.000967 < x < √43104519/1000 或  12.284153 < x < 12.848588
