    Assignment:Find the solution set of inequality 67.5-2/tan(x)-67.5/2/sin(x)/sin(x) >1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        67.5 - 2 / tan ( x ) - 67.5 / 2 / sin ( x ) / sin ( x ) >1         (1)

---

    From inequality(1)：
         x < -7.061066 或  -5.475238 < x < -3.919473 或  -2.333646 < x < -0.777881 或  0.807947 < x < 2.363712 或  3.94954 < x < 5.505305 或  x ＞ 7.091132

---

    The final solution set is :
         x < -7.061066 或  -5.475238 < x < -3.919473 或  -2.333646 < x < -0.777881 或  0.807947 < x < 2.363712 或  3.94954 < x < 5.505305 或  x ＞ 7.091132
