Discussion Overview

The discussion revolves around the inequality (1 + 1/m)^m > (1 + 1/n)^n, with participants exploring the possibility of proving this statement given the conditions m > n > 0. The scope includes mathematical reasoning and derivative analysis.

Discussion Character

  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • One participant questions how to prove the inequality (1 + 1/m)^m > (1 + 1/n)^n.
  • Another participant suggests that proving the inequality may not be possible, but finding solutions for m or n could be an alternative approach.
  • There is a discussion about the nature of the statement, with one participant noting that it involves two variables and one statement, which complicates direct proof.
  • A participant expresses confusion and requests clarification on the proof process.
  • One participant introduces the function y = (1 + 1/x)^x and seeks to prove that its derivative y' > 0.
  • Another participant advises finding the derivative of (1 + 1/x)^x as a step towards understanding the inequality.
  • There are requests for assistance in finding the derivative, with one participant admitting difficulty in doing so.
  • One participant emphasizes the importance of not simply providing answers, suggesting that using derivative calculators could be beneficial.

Areas of Agreement / Disagreement

Participants do not reach a consensus on whether the inequality can be proven. There are competing views on the approach to take, with some focusing on finding solutions and others on derivative analysis.

Contextual Notes

The discussion highlights the complexity of proving the inequality due to the presence of two variables and the nature of the mathematical statement involved. There are also language barriers affecting communication among participants.

m > n >0

How can can prove that (1 + 1/m )^m > ( 1 + 1/n )^n ?

Thank you very much.
 
Mathematics news on Phys.org
You can't prove it, but you could solve for an m or n that describes the possible solutions.
 
Why that we can't prove it?
 
You've got 2 variables and 1 statement.
 
oh, I couldn't understand!
Can you explain for me?
Thank you!
 
I should've asked from the beginning, but what are you trying to prove? (1 + 1/m )^m > ( 1 + 1/n )^n is a statement. The only information you could get from that statement is the solutions to m in terms of n or solutions to n in terms of m.
 
y= (1 +1/x)^x
I want to know how to prove that : y' >0
 
All you have to do is find the derivative of (1 + 1/x)x.
 
oh!
could you help me to find the derivative of (1 + 1/x)^x ?
 
  • #10
I'll help. Show what you've got.
 
  • #11
thank you very much.
I can't find derivative of (1 + 1/x)^x, so I haven't got anything...
 
  • #12
oh... sorry
but I am not good at English subject. I couldn't find the word that I want to say.
 
  • #13
I'm not going to just give you the answer. There would be no good in that. There are sites that can find derivatives. http://www.wolframalpha.com/ is one of them.
