You look a little thin, have you been eating?

What are you talking about?

My friend Sneha has this problem

Okay, here is a proof.

Construct a sequence with elements in S such that all terms are different. This should be possible because S is infinite. Now, because this sequence is bounded, it must have a convergent subsequence which is non-constant.

Hence, it follows that S' is non-empty.

Have you seen the proof of the fact that there is a rational number between any two reals?

#6 Re: Exercises » Limit Points of a Set » 2016-10-22 18:46:48

By S', do you mean the set of all limit points of S?

You are right. I should tell him about online compilers.

No, I didn't miss the rants. Is that even possible?

That code is fine. But the point of my code was to demonstrate an overflow

I once claimed in some forum that the following code in C is an infinite loop:

#include <stdio.h>

int main(void) {
    char i;
    for (i=0; i <256; i++)
        printf("%d\n", i);
    return 0;
Somebody wrote:

How is this program an infinite loop? Unless char I doesn't increment because it's a character and not an integer.

I wrote:

Before I go ahead and answer that question, I personally encourage you to actually put this in a compiler and run the code for yourself and check that it indeed is an infinite loop.

Somebody wrote:

I don't have a compiler, but I know enough about coding to know that for loops shouldn't be infinite loops. So if it doesn't output integers, then it must be an error of sort.

What?! How can someone not have a compiler but *know enough about coding*?

But why is the manifold expanding?

#12 Re: Euler Avenue » The metaproblem problem » 2016-10-09 03:29:06

Why did you do that? I do not think you ran out of delta waves.

#13 Re: Euler Avenue » The metaproblem problem » 2016-10-09 03:00:24

Which problems did you stop posting?

I think everybody has hard of Joseph Fourier. I do not read Rudin because it lacks motivation for the reader.

We are trying to post problems for general public on the internet. Of course there are some hard problems for the Level 5 guys

#16 Re: Euler Avenue » The metaproblem problem » 2016-10-05 15:45:11

Yes, and interesting questions are not necessarily difficult questions

#17 Re: Euler Avenue » The metaproblem problem » 2016-10-05 05:42:37

But this thread is about the metaproblem problem

#18 Re: Euler Avenue » The metaproblem problem » 2016-10-04 18:37:16

Our analysis professor thinks Rudin is ruining Analysis

#19 Re: Euler Avenue » The metaproblem problem » 2016-10-04 17:56:59

I asked PiHan on the metaproblem problem. He asked me to look at Rudin and not do any of it.

Have you seen the book named "Visual Group Theory"?
