[ 1/1Inequality]
Assignment:Find the solution set of inequality 2*(1/3)^(2n-1)/(2n-1) <0.0001 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
2 * ( 1 / 3 ) ^ ( 2 * n - 1 ) / ( 2 * n - 1 ) <0.0001 (1)
From the definition field of divisor
2 * x - 1 ≠ 0 (2 )
From inequality(1):
n < 0.5 或 n > √8437169/√500000
From inequality(2):
n < 1/2 或 n > 1/2
From inequalities (1) and (2)
n < 0.5 或 n > √8437169/√500000 (3)
The final solution set is :
n < 0.5 或 n > √8437169/√500000Your problem has not been solved here? Please take a look at the hot problems !
