[ 1/3Inequality]
    Assignment:Find the solution set of inequality sin(x) >0.2 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         sin ( x ) >0.2         (1)

---

    From inequality(1)：
         x < -15.909321 或  -12.365013 < x < -9.626136 或  -6.081827 < x < -3.342951 或  0.201358 < x < 2.940235 或  6.484543 < x < 9.22342 或  x ＞ 12.767729

---

    The final solution set is :
         x < -15.909321 或  -12.365013 < x < -9.626136 或  -6.081827 < x < -3.342951 或  0.201358 < x < 2.940235 或  6.484543 < x < 9.22342 或  x ＞ 12.767729

[ 2/3Inequality]
    Assignment:Find the solution set of inequality x+2 >12 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         x + 2 >12         (1)

---

    From inequality(1)：
         x ＞ 10

---

    The final solution set is :
         x ＞ 10
