Assignment:Find the solution set of inequality (e(-0.413x)-e(-0.4543x))/(1.8159-e(-0.413x)) <0.01 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( e ( -0.413 * x ) - e ( -0.4543 * x ) ) / ( 1.8159 - e ( -0.413 * x ) ) <0.01 (1)
From the definition field of divisor
1.8159 - e ( -0.413 * x ) ≠ 0 (2 )
From inequality(1):
-1.444507 < x < 0.245771 或 x > √38603669/1000
From inequality(2):
x < -1.444507 或 x > -1.444507
From inequalities (1) and (2)
-1.444507 < x < 0.245771 或 x > √38603669/1000 (3)
The final solution set is :
-1.444507 < x < 0.245771 或 x > √38603669/1000Your problem has not been solved here? Please take a look at the hot problems !
