    Assignment:Find the solution set of inequality sin(tanx) <1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         sin ( tan x ) <1         (1)

---

    From inequality(1)：
         x < -1697439/1000000 或  -1697439/1000000 < x < -340423/250000 或  -340423/250000 < x < 250971/250000 或  250971/250000 < x < 1.444153 或  1.444153 < x < 1779901/1000000 或  x ＞ 1779901/1000000

---

    The final solution set is :
         x < -1697439/1000000 或  -1697439/1000000 < x < -340423/250000 或  -340423/250000 < x < 250971/250000 或  250971/250000 < x < 1.444153 或  1.444153 < x < 1779901/1000000 或  x ＞ 1779901/1000000
