[ 1/1Inequality]
Assignment:Find the solution set of inequality e(-Xπ/√(1-X^2))×100% <5% .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
e ( -X * π / √ ( 1 - X ^ 2 ) ) × 100 % <5 % (1)
From the definition field of √
1 - x ^ 2 ≥ 0 (2 )
From inequality(1):
X < -1 或 X > 0.690107
From inequality(2):
-1 ≤ X ≤ 1
From inequalities (1) and (2)
0.690107 < X ≤ 1 (3)
The final solution set is :
0.690107 < X ≤ 1 Your problem has not been solved here? Please take a look at the hot problems !
