[ 1/1Inequality]
    Assignment:Find the solution set of inequality (3k^3-3k+6)/(k^3-2) >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
         ( 3 * k ^ 3 - 3 * k + 6 ) / ( k ^ 3 - 2 ) >0         (1)
        From the definition field of divisor
         x ^ 3 - 2 ≠ 0        (2 )

    From inequality(1):
         k < -1.52138 或  k > 1.259921
    From inequality(2):
         k < 1.259921 或  k > 1.259921

    From inequalities (1) and (2)
         k < -1.52138 或  k > 1.259921    (3)

    The final solution set is :

         k < -1.52138 或  k > 1.259921
