[1/2 Formula]
Work: Calculate the value of equation 1-e^2+1/1-e .
Question type: Mathematical calculation
Solution:
1-e^2+1/1-e
=1-2.718282^2+1/1-e
=1-2.718282^2+1/1-2.718282
=1-7.389057031524+1/1-2.718282
=1-7.389057031524+1-2.718282
=-6.389057+1-2.718282
=-5.389057-2.718282
=-8.107339
Answer:1-e^2+1/1-e=-8.107339
[ 2/2Inequality]
Assignment:Find the solution set of inequality ^2－3 ≤0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality：
2 - 3 ≤0 (1)
From inequality(1)：
∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
The final solution set is :
∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
