[ 1/1Inequality]
    Assignment:Find the solution set of inequality 0 <1510/[180(n-2)] <180 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        0 <1510 / ( 180 * ( n - 2 ) )         (1)
        1510 / ( 180 * ( n - 2 ) ) <180         (2)
        From the definition field of divisor
         180 * ( x - 2 ) ≠ 0        (3 )

---

    From inequality(1)：
         n ＞ 2
    From inequality(2)：
         n < 2 或  n ＞ 2.046605
    From inequality(3)：
         n < 2 或  n ＞ 2

---

    From inequalities (1) and (2)
         n ＞ 2.046605    (4)
    From inequalities (3) and (4)
         n ＞ 2.046605    (5)

---

    The final solution set is :
         n ＞ 2.046605
