    Assignment:Find the solution set of inequality (1.35/(0.85*(2*9.81)^(1/2)*tan(x/2)*(8/15)))^(2/5) <0.5 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 1.35 / ( 0.85 * ( 2 * 9.81 ) ^ ( 1 / 2 ) * tan ( x / 2 ) * ( 8 / 15 ) ) ) ^ ( 2 / 5 ) <0.5         (1)
        From the definition field of divisor
         0.85 * ( 2 * 9.81 ) ^ ( 1 / 2 ) * tan ( x / 2 ) * ( 8 / 15 ) ≠ 0        (2 )

---

    From inequality(1)：
        The solution set is empty, that is, within the range of real numbers, the inequality will never be established!
    From inequality(2)：
         x < -15.707963 或  -15.707963 < x < -12.566371 或  -12.566371 < x < -9.424778 或  -9.424778 < x < -6.283185 或  -6.283185 < x < -3.141593 或  -3.141593 < x < 0 或  0 < x < 3.141593 或  3.141593 < x < 6.283185 或  6.283185 < x < 9.424778 或  9.424778 < x < 12.566371 或  x ＞ 12.566371

---

    The final solution set is :
        The solution set is empty,that is, the inequality will never be estatlished within the real number range.
