[ 1/1Inequality]
Assignment:Find the solution set of inequality e^x-1/2x^2 >ln(x-1)+x^e .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
e ^ x - 1 / 2 * x ^ 2 > ln ( x - 1 ) + x ^ e (1)
From the definition field of ln
x - 1 > 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 > 1
From inequalities (1) and (2)
x > 1 (3)
The final solution set is :
