    Assignment:Find the solution set of inequality −cos(−x+101.72) <0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        -cos ( -x + 101.72 ) <0         (1)

---

    From inequality(1)：
         -12.948132 < x < -9.806539 或  -6.664947 < x < -3.523354 或  -0.381761 < x < 2.759831 或  √17413403/√500000 < x < 9.043017 或  12.184609 < x < 15.326202

---

    The final solution set is :
         -12.948132 < x < -9.806539 或  -6.664947 < x < -3.523354 或  -0.381761 < x < 2.759831 或  √17413403/√500000 < x < 9.043017 或  12.184609 < x < 15.326202
