[ 1/1Inequality]
Assignment:Find the solution set of inequality e(-3.14*x/√(1-x^2)) <0.1 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
e ( -3.14 * x / √ ( 1 - x ^ 2 ) ) <0.1 (1)
From the definition field of √
1 - x ^ 2 ≥ 0 (2 )
From inequality(1):
x < -1 或 x > 0.59135
From inequality(2):
-1 ≤ x ≤ 1
From inequalities (1) and (2)
0.59135 < x ≤ 1 (3)
The final solution set is :
0.59135 < x ≤ 1 Your problem has not been solved here? Please take a look at the hot problems !
