---

    From inequality(1)：
         -31.415927 < x < -28.274334 或  -25.132741 < x < -21.991149 或  -18.849556 < x < -15.707963 或  -12.566367 < x < -9.424859 或  -6.281314 < x < -3.183063

---

    The final solution set is :
         -31.415927 < x < -28.274334 或  -25.132741 < x < -21.991149 或  -18.849556 < x < -15.707963 或  -12.566367 < x < -9.424859 或  -6.281314 < x < -3.183063
