Assignment:Find the solution set of inequality (1-0.187e(-1.923x))/(1-0.187e(-2.1153x)) >0.99 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 1 - 0.187 * e ( -1.923 * x ) ) / ( 1 - 0.187 * e ( -2.1153 * x ) ) >0.99 (1)
From the definition field of divisor
1 - 0.187 * e ( -2.1153 * x ) ≠ 0 (2 )
From inequality(1):
x > -0.792628
From inequality(2):
x < -0.792628 或 x > -0.792628
From inequalities (1) and (2)
x > -0.792628 (3)
The final solution set is :
x > -0.792628Your problem has not been solved here? Please take a look at the hot problems !
