Hi;

How about using what you know about the growth of functions?

Hi bobbym

I thought of asymptotic analysis as well, but I'm not sure how to use out properly.

Doesn't x^x^x grow faster than e^x^x when x > e?

Hi bobbym

Well it does, but how do I formally show that? Or is that not necessary?

We are not looking for a formal idea here just a good solid reason why it might be so.

Also, do you really need a formal prove utilizing the sandwich theorem from topology to see that x^x^x grows faster than e^x^x?

Yep, you are right. That question stretches the limits of this thread. I have removed it and banned the poster.

Hi bobbym

Could you delete my reply to that post as well?

Next problem?

Hi bobbym

Ok thanks.

You think of those problems? Why don't you just find some online?

That is correct! Very good. I think you know how to do a limit.

Hi bobbym

Why wouldn't I know? Didn't I do limits before?

If you know and I know you know and you know that I know you know how, then why do you need anymore?

Hi bobbym

Well why don't you give some harder?

Btw, I need help with this:

Given the function f(x)=

Find the real numbers a and b such that

f(x)=lxl*(a+b/x+o(1/x))

As x goes to infinity.

Cause then you would not be able to do them or I would not. What sense does that make?

Take and post that in help me in a new topic. Someone will help you with it.

Hi bobbym

You don't have to go overboard with the difficulty level. Choose some not so tough, but tough enough to represent a challenge.

No, I meant this is gAr's thread and not mine. Here he poses the problems, not me. Also, I am totally out of ideas.

Hi bobbym

That sound just like a poor excuse. gAr didn't mind you posing problems here so far, I think he wouldn't mind now, but of you don't have ideas them you should just say so!

I did. Questions are difficult to pose, even harder than solving them. I have some questions for the other thread. And my point is your knowledge of limits is fine.

I have some problems for the other thread on asymptotics. Anyway, gAr is posting better problems.
