[ 1/1Inequality]
    Assignment:Find the solution set of inequality abs(cosx-1+1/2x^2-1/24x^4) <1/999 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
         abs ( cos x - 1 + 1 / 2 * x ^ 2 - 1 / 24 * x ^ 4 ) <1 / 999         (1)

    From inequality(1):
         -√6309757/√7000000 < x < √6309757/√7000000

    The final solution set is :

         -√6309757/√7000000 < x < √6309757/√7000000
