[ 1/1Inequality]
    Assignment:Find the solution set of inequality sinx = 2*sin(3*x-30)x >0x <360 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
         sin x 2 * sin ( 3 * x - 30 ) * x >0 * x         (1)
        0 * x <360         (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 ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!

---

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