[ 1/1Inequality]
Assignment:Find the solution set of inequality π/4
Solution:
The inequality can be reduced to 2 inequalities：
π / 4 < x (1)
x < π / 2 (2)
From inequality(1)：
x ＞ 0.785398
From inequality(2)：
x < 1.570796
From inequalities (1) and (2)
0.785398 < x < 1.570796 (3)
The final solution set is :
0.785398 < x < 1.570796
