[ 1/1Inequality]
    Assignment:Find the solution set of inequality tan(x)-x/180 = 0.5/637100000x <90 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         tan ( x ) - x / 180 0.5 / 637100000 * x <90         (1)

---

    From inequality(1)：
         x < -183.78317 或  -183.78317 < x < -174.369503 或  -174.358392 < x < -164.944725 或  73.827427 < x < 83.241095 或  83.252205 < x < 92.665873 或  x ＞ 92.665873

---

    The final solution set is :
         x < -183.78317 或  -183.78317 < x < -174.369503 或  -174.358392 < x < -164.944725 或  73.827427 < x < 83.241095 或  83.252205 < x < 92.665873 或  x ＞ 92.665873
