Can U Prove 3=2??
-
This is something that i received in mail. very intresting. And I am sorry if this is a repost. :) Can U Prove 3=2?? Here is Proof for 3=2 from Ramanujam. This seems to be an anomaly or whatever u call in mathematics.It seems, Ramanujam found it but never disclosed it during his life time and that it has been found from his dairy. See this illustration: -6 = -6 9-15 = 4-10 adding 25/4 to both sides: 9-15+(25/4) = 4-10+(25/4 ) Changing the order 9+(25/4)-15 = 4+(25/4)-10 (this is just like : a square + b square - two a b = (a-b)square. ) Here a = 3, b=5/2 for L.H.S and a =2, b=5/2 for R.H.S. So it can be expressed as follows: (3-5/2)(3-5/ 2) = (2-5/2)(2-5/ 2) Taking positive square root on both sides: 3 - 5/2 = 2 - 5/2 3 = 2 ANY FLAWS??????? ???????

That's a big rumour. Ramanujam will not waste his time on this silly proof. This is an hold high school trick, I might have found funny when I was in high school not anymore. X|

a = b<=> a² = ab
<=> a² + a² - 2ab = ab + a² - 2ab
<=> 2a² - 2ab = a² - ab
<=> 2(a² - ab) = 1(a² - ab)
<=> 2 = 1Is this a proof by contradiction that for any a,b, a cannot equal b?

Well, it's quite common for people wanting to spread something and have people read it without thinking it through, to claim it comes from someone well known. It's a bit like those fake virus emails that say 'this is top of Microsoft's 'most dangerous virus list'' ( there is no such list )
Christian Graus - Microsoft MVP - C++ Metal Musings - Rex and my new metal blog "I am working on a project that will convert a FORTRAN code to corresponding C++ code.I am not aware of FORTRAN syntax" ( spotted in the C++/CLI forum )
yes. But i just wonder on how much impact the little things can have on us. Just a line reading -"This was found in Ramanujam's dairy!" made me not to look for flaws in the (so called) 'proof'. Honestly, when i was in Pre University Collage (6 years back), i knew a trick by which we used to prove 1=2. i knew it was a trick and not the truth. but since the similar kind of trick was used to prove 2=3 and said that it was a proof by Ramanujam, they made me belive in the false proof and accept it without a second thought.

Hey, proof for 2 = 1. This is the trick i was speaking about in my reply to christian's post. :)

This tep is wrong, (a² - ab) is Zero, division by zero is undefined (not valid)
C++ where friends have access to your private members !
you got it right. But when I was in High School, i used the same trick to prove 2=1 to my friends and most of my friends were unable to find where the trick was. It took them some time to figure out the trick. :)

Step 5: (3-5/2)^2 = (2-5/2)^2 => 1/2 ^2 = -1/2 ^2 From this, though, you can't say 1/2 = -1/2

Yes. Division by zero.

As he explicitly said "Taking positive square root", sqrt(x^2) = |x| Therefore, |0.5| = |-0.5| which is clearly equivalent to -6=-6.
The positive square root does not mean taking the absolute value of the negative square root. 4 has to two roots +2 and -2. The positive square root of 4 is +2. 2 - 5/2 is not the positive square root it is the negative square root (2 - 2/5 = -1/2) the positive square root is +1/2 or 2/5 - 2 and the proof leaves 1/2 = 1/2. I see was I too slow typing see Chris below

Yup... he hand waved it by saying "Take the positive square root" but that's not a legal step.

Well, you can say "Take the positive square root". But the positive square root of -1/2^2 is 1/2, not -1/2. So when you take the positive square root of x^2, you have to write |x| to ensure that it's the positive one.
