[ 1/1Inequality]
Assignment:Find the solution set of inequality ex+e-x <2/x .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
e x + e -x <2 / x (1)
From the definition field of divisor
x ≠ 0 (2 )
From inequality(1):
x < -2.451671 或 0 < x < 0.796536
From inequality(2):
x < 0 或 x > 0
From inequalities (1) and (2)
x < -2.451671 或 0 < x < 0.796536 (3)
The final solution set is :
x < -2.451671 或 0 < x < 0.796536 Your problem has not been solved here? Please take a look at the hot problems !
