Assignment:Find the solution set of inequality e^x+2/x^2 >0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
e ^ x + 2 / x ^ 2 >0 (1)
From the definition field of divisor
x ≠ 0 (2 )
From inequality(1):
x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
From inequality(2):
x < 0 或 x > 0
From inequalities (1) and (2)
x < 0 或 x > 0 (3)
The final solution set is :
x < 0 或 x > 0Your problem has not been solved here? Please take a look at the hot problems !
