[ 1/1Inequality]
Assignment:Find the solution set of inequality 0.99 <(1000(1-e^(-60/(10001*x)))/60/x ) .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
0.99 < ( 1000 * ( 1 - e ^ ( -60 / ( 10001 * x ) ) ) / 60 / x ) (1)
From the definition field of divisor
10001 * x ≠ 0 (2 )
From the definition field of divisor
x ≠ 0 (3 )
From inequality(1):
-0.319304 < x < 0.316304
From inequality(2):
x < 0 或 x > 0
From inequality(3):
x < 0 或 x > 0
From inequalities (1) and (2)
-0.319304 < x < 0 或 0 < x < 0.316304 (4)
From inequalities (3) and (4)
-0.319304 < x < 0 或 0 < x < 0.316304 (5)
The final solution set is :
-0.319304 < x < 0 或 0 < x < 0.316304 Your problem has not been solved here? Please take a look at the hot problems !
