[ 1/4Inequality]
Assignment:Find the solution set of inequality e^(-a^2) >= 1/4, .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality：
e ^ ( -a ^ 2 ) >= 1 / 4 , (1)
From inequality(1)：
-1.17741 ≤ a ≤ 1.17741
The final solution set is :
-1.17741 ≤ a ≤ 1.17741[ 2/4Inequality]
Assignment:Find the solution set of inequality e^(-a^2) <= 3/4, .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality：
e ^ ( -a ^ 2 ) <= 3 / 4 , (1)
From inequality(1)：
a ≤ -0.53636 或 a ≥ 0.53636
The final solution set is :
a ≤ -0.53636 或 a ≥ 0.53636[ 3/4Inequality]
Assignment:Find the solution set of inequality (2*a^2-1)e^(-a^2) >= -1/4, .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality：
( 2 * a ^ 2 - 1 ) * e ^ ( -a ^ 2 ) >= -1 / 4 , (1)
From inequality(1)：
