    Assignment:Find the solution set of inequality sinx     Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
         sin x < x         (1)
         x < tan x         (2)

---

    From inequality(1)：
         x ＞ 0
    From inequality(2)：
         x < -7.853982 或  -7.725252 < x < -4.712389 或  -4.493409 < x < -1.570796 或  0 < x < 1.570796 或  4.493409 < x < 4.712389 或  x ＞ 7.725252

---

    From inequalities (1) and (2)
         0 < x < 1.570796 或  4.493409 < x < 4.712389 或  x ＞ 7.725252    (3)

---

    The final solution set is :
         0 < x < 1.570796 或  4.493409 < x < 4.712389 或  x ＞ 7.725252
