what the 4 colour theorem???

Thank you.
its really interesting stuff. . just came to know about this yesterday morning ...Originally Posted by dennis
apparently .. mathematicians have been goin nuts for 100 years just to solve this problem .. it was posed by a silly student .. and it made mathematicians spend more than hundreds of thousands of hours just ot solve this problem ..
it says .. to colour a map .. any map .. you need not more than 4 colours, so that any neighbouring country would not have the same colour filled in ... easy said than done .. hehe
ohh...coool, thanks for the info and the link too.

Dudes I can prove that equation wrong. See this:
n^2 - n -41 = never divisible by 7
To prove it wrong, we have to prove that for a certain value of n, the answer must b divisible by 7. So we work counter-clock wise, we put the equation equal to anything divisible by 7. Now watch:
n^2 - n - 41 = 7
=> n^2 - n = 7+41
=> n(n-1) = 48
Now either n=48, or (n-1)=48. So we put n=48 in the above equation
48^2=2304
48^2 - 48 - 41=7
2215=7 (I know it doesn't sound right, but for the time being.....)
When we divide 2215 by 7, it gives 316.428. Not a whole nmber. Now try the other equation. i.e., n-1=48 => n=47
Putting in equation:
47^2=2209
47^2 - 47 -41=7
2209 - 47 - 41=7
2121=7
This solves to give the answer 303. A perfect whole number. I know nobody asked for a proof, Just for the fun...... Peace

underlining assumption ::
(n2-n-41 )/7 =1
which is not the case
at most we can do is
(n2-n-41)/7 = x ...x being a postive or negative whole number
things we can arrive after assuming n2-n-41 divisible by 7
are for example
(n2-n-41 -7)(n2-n-41+7)(x) =0 ....
where x is any postive or negative integer.....

n(n-1)=48..and u say n= 48
if n= 48 then n(n-1) =48*47 and not 48...caught u there
the answer is between 8 and 7 cuz for 8 n(n-1) =56 and for 7 its 42

Yea ur absolutely right dude. But i took some alien method of my own invention to get to the point. Put n = 47, and u have an answer divisible by 7. Thats the game!
JEE mein sabse weak was Math; Mathematical Induction especially.
And seeing you fellows ramble here
You don’t get what you deserve, you get what you negotiate.
Dudes, I know my method is WEEEEEEEEE controversial, but i gave u the right answer. Didnt I? Now leave my thing alone... It wont make sense to many in the world, but it makes good sense to me. U got the answer, thats all what matters.
n2 - n - 41 = 7x where x=any real number. For any value of x, the relative value of n is right answer. Suit urselves. Its the closest i can get to common-to-the-world maths. Bye
n2-n-41 = x
assuming x is divisible by 7
therefore
(x-7)(x+7)(y)=0
when y is any number greater not equal to 0
therefore x2-49 =0
(n2 -n-41)2-49=0
or
(n2-n-41-7)(n2-n-41+7)=0
i.e. either
n2-n-48 =0
n2-n-34=0
none of them is factoriable ...there is one theorem to prove that...(something ac>b2)types dont exactly recall that...
so in turn n will come out to be an imaginary number.....
now the value of n2-n-41 will in turn be an imaginary number....
so the first assumption that x or n2-n-41 is divisible by 7 is wrong....
...this is not the complete ...but should be on the lines of solution....
