Hm, thanks for digging this thread up.

#2 Re: Help Me ! » Simplify the following: » 2014-08-27 06:00:33

That's the same thing as the last one.

#3 Re: This is Cool » Find all the prime numbers in a given range.... » 2014-08-27 05:56:26

That is incorrect. For example, 25 would remain after the process, but is not prime.

Hi PatternMan

Do you remember how the absolute value of a number is defined?

Hi iluvdogs

Welcome to the forum! smile

What is your favourite fur color?

That said, I think both of you have asked incorrect questions. smile

#9 Re: Help Me ! » I have proved Goldbach's theorem can someone check it for me? » 2014-08-16 21:34:19

I don't think "proving it" probabilistically does not actually prove it, just shows it's true in many cases, unless I'm missing something.

Hi Olinguito

Welcome to the forum! smile

What's your favourite colour?

Assuming y is the number of cubes, the formula is y=e^3/x^3.

#12 Re: Help Me ! » Circle Geo Problems » 2014-08-09 01:03:00

I'v also had that problem with the word "p.o.k.e.r".

#13 Re: Jokes » Math Pick-up Lines » 2014-08-07 02:14:00

The first and third one are plays on familiar and cheesy pickup lines.

#16 Re: Help Me ! » Derivative of Ln(x) » 2014-08-01 05:07:51

Is there any way you could post a picture of that or maybe use LaTeX?

#17 Re: Help Me ! » Derivative of Ln(x) » 2014-08-01 02:48:31

Hm, it's all mixed up. How is 1/ln(g) * ln(x) = (1/ln(g)) * (1/x) ?

#18 Re: Jokes » Math Pick-up Lines » 2014-07-31 10:23:15

That doesn't mean it does not have meaning.

#19 Re: Jokes » Math Pick-up Lines » 2014-07-31 06:21:03

The number 3 does not exist either, then.

#20 Re: Help Me ! » Does this sequence converge or diverge? » 2014-07-30 10:00:45

That sounds right. The only exception (that I can think of) is any constant sequence.

#21 Re: Help Me ! » Does this sequence converge or diverge? » 2014-07-30 03:03:50

sin(n) would be oscillating, but not periodic.

#23 Re: Jokes » Math Pick-up Lines » 2014-07-29 05:45:53

Maybe he has to simulate if the pickup line works.

#24 Re: Help Me ! » 3d geometry? » 2014-07-27 07:53:41

No problem. smile

The volume is now easy to compute.

#25 Re: Coder's Corner » Is Anyone using BASIC Anymore? » 2014-07-27 07:51:19

I participated in the competition organized by our country, but that's pretty much it.
