emm, i would like to use my first helping tools. i need some hint.
is the question you posted is err on the fundamental logic or err on the way/equation that was presented/written up there?

The proof is written wrongly (intentionally of course). You must find a way to correct it so that mathematically it is either correct, or at the least, comes to a proper conclusion without some weird non-sensible result.

Why non-sensible? pi has nothing to do with it. You can put there y and you arrive at the conclusion that x=y if you take the positive root Very Happy (pi just a random variable here...)

well, borsuc.
if 2x = y + 3 is ==> y = 2x -3
then how come y = 3 in the end.

2x = y + 3

x = 3
y = 3

==> 2*3 = 3 + 3

6 = 6 Wink

x=y (y, no matter what it is! there's nothing special here about 'pi')

if you change x=4 and y = 5
so 2(4) = 5+3

it will count correct until this line.
3 - x = y - x

Okay, so you discovered my slight distraction about making it pi. Yes, the "pi" variable is just a distraction to attempt to throw the unwary off the scent for a short while. Hehe, seems to have worked as intended. Very HappyRazzCoolTwisted Evil But, of course, that is not the answer. I'm still waiting ...

Code:
If          x = (a + n) / 2       ;x is the average of 2 constants a, n
then       2x = a + n
and 2x(a - n) = a^2 - n^2     ;multiply by the difference of a and n
so a^2 - 2x(a - n) - n^2 = 0
=> a = n                   ;is only valid if a = n i.e. a - n = 0

e.g.          x = (p + 3) / 2
     .....
       .....
=> p = 3 = x


            x = (q + 4) / 2
            .....
        .....
=> q = 4 = x

Haha. LOL.

I would be very happy to give you the star, but you must work hard for it (they are expensive and thus not given freely). Your "answer" above is not correct, sorry no star just yet!

Hehe, these days it seems there is no need to think anymore, what with the 'net available it has all the answers to the questions anyone could ever ask.

emm..
i think this line weird.
9 - 6x = pi^2 - 2pix
9 - 6x + x^2 = pi^2 - 2pix + x^2

it must be
(9 - 6x) + x^2 = (pi^2 - 2pix) + x^2

so, this
(3 - x)^2 = (pi - x)^2 is invalid. because (9 - 6x) and (pi^2 - 2pix) must be solve first before integrate with x^2.

well, if it is still incorrect, i wait for ur answer then.
Smile i like maths, but i am not doing so well with it.

Heh that's until you NEED to make up your own algorithms to fit your purpose (as a guy who programmed 3D software, I do know how math should be 'visualized', not by learning formulas Wink).

Is it because of pi^2, that taking the square root means the absolute value of it? (not original number) Smile

I mean, when 'expanding' (pi + 3)(pi - 3) -- it only works the other way around? (otherwise it is absolute value) Confused

The attempts so far seem to be sort of on the right track, but so far no one has yet been able to bring all the ideas together into a full coherent answer.

There are bits of an answer here and parts of an answer there etc.

Ah, such impatience. There are currently three open puzzles not solved in this thread. To which are you referring?

Ok, I'm probably wrong and looking stupid here but.....

If Pi does indeed equal 3, then on line 4 you would be dividing by zero to remove the (pi-3), because (3-3)=0. Thus making the formula FALSE, right?
Code:
x = (pi + 3) / 2
    x=(3+3)/2=3

2x = pi + 3
    6=6

2x(pi - 3) = (pi + 3)(pi - 3)
    0=6(0)

2pix - 6x = pi^2 - 9
    YOU DIVIDED BY ZERO TO REMOVE (pi-3), the rest is just filler to make it look real

      9 - 6x = pi^2 - 2pix

9 - 6x + x^2 = pi^2 - 2pix + x^2

   (3 - x)^2 = (pi - x)^2

       3 - x = pi - x

          pi = 3    


I WANT ANOTHER STAR lol
