Assignment:Find the solution set of inequality abs(sin(x)*x) ≤abs(x) .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality：
abs ( sin ( x ) * x ) ≤ abs ( x ) (1)
From inequality(1)：
x ≤ -3926991/500000 或 -3926991/500000 ≤ x ≤ -4712389/1000000 或 -4712389/1000000 ≤ x ≤ -4712389/1000000 或 -4712389/1000000 ≤ x ≤ -1570797/1000000 或 -1570797/1000000 ≤ x ≤ -1570797/1000000 或 -1570797/1000000 ≤ x ≤ 0 或 0 ≤ x ≤ 0 或 0 ≤ x ≤ 1570797/1000000 或 1570797/1000000 ≤ x ≤ 1570797/1000000 或 1570797/1000000 ≤ x ≤ 4712389/1000000 或 x ≥ 4712389/1000000
The final solution set is :
x ≤ -3926991/500000 或 -3926991/500000 ≤ x ≤ -4712389/1000000 或 -4712389/1000000 ≤ x ≤ -4712389/1000000 或 -4712389/1000000 ≤ x ≤ -1570797/1000000 或 -1570797/1000000 ≤ x ≤ -1570797/1000000 或 -1570797/1000000 ≤ x ≤ 0 或 0 ≤ x ≤ 0 或 0 ≤ x ≤ 1570797/1000000 或 1570797/1000000 ≤ x ≤ 1570797/1000000 或 1570797/1000000 ≤ x ≤ 4712389/1000000 或 x ≥ 4712389/1000000 *Note: Radian.Your problem has not been solved here?
