[ 1/1Inequality]
    Assignment:Find the solution set of inequality (8/3×tan(x+π/2))^2-4×((tan(x+π/2))^2+1)×(-17/36) <0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 8 / 3 × tan ( x + π / 2 ) ) ^ 2 - 4 × ( ( tan ( x + π / 2 ) ) ^ 2 + 1 ) × ( -17 / 36 ) <0         (1)

---

    From inequality(1)：
        The solution set is empty, that is, within the range of real numbers, the inequality will never be established!

---

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