    Assignment:Find the solution set of inequality (1330+30*b^2)/b^2+980*6/b^3 <= 360 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 1330 + 30 * b ^ 2 ) / b ^ 2 + 980 * 6 / b ^ 3 <= 360         (1)
        From the definition field of divisor
        x ≠ 0        (2 )
        From the definition field of divisor
        x ≠ 0        (3 )

---

    From inequality(1)：
         b ≤ -0.0001 或  b ≥ 3.12085
    From inequality(2)：
         b < 0 或  b ＞ 0
    From inequality(3)：
         b < 0 或  b ＞ 0

---

    From inequalities (1) and (2)
         b ≤ -0.0001 或  b ≥ 3.12085    (4)
    From inequalities (3) and (4)
         b ≤ -0.0001 或  b ≥ 3.12085    (5)

---

    The final solution set is :
         b ≤ -0.0001 或  b ≥ 3.12085
