Food goes in here
Lol, this topic has gone off on a tangent, but I don't blame you guys, this run's taking longer than Duke Nukem Forever.:P Or whatever the hell its called now.

So e^x goes up to the operator and says, "I'm e^x. You can't do anything to me!"
And the operator says, "Hi, I'm d/dy."

If I remember anything from multivariable,      d(ex) / dy          =        0          right?

Now i'm waiting for an edit that goes:
Finally...scenes from Half-Life in Half an Hour!
No way, they've actually been working on it??

Sorry but you are wrong, the answer is 0 because e^x is not a function of y, thus it's derivative in relation to y (sorry if I am using the wrong words, don't know the correct terms in English) is 0.

lool guys!

now: f(x,y)=(X²-Y²)/(1-X)  (R-{1})

calculate df/dxdy
and after, df/dydx

what can you say me about this function, according to Cauchy, to prevent the coming of spider's run? Grin Grin Grin ^^

I loved Highschool, knowing that it's finished lol

df/dxdy  =  df/dydx  =  [(-2y)(x2 - 2x + 1)] / [(1 - x)4]

yeaaah, there is a demonstration which prove that, it was funny because it seemed to be impossible^^
but there is a little mistake in this demonstration, which create this error Grin

Edit your post and give me the details of your calculs, you may find the same! Iwill found the demonstration for 0,9999=1, if I remember how to get it Grin

Isn't that just:

x = 0.999999...

10x = 9.999999...

9x = 10x - x = 9

x = 1

0.999999... = 1

I don't remember too well... I suspect there's a more complicated way but that's easy enough.

it is like this but it is not 10x-x=9 Wink

EDIT: infact, it may be this demonstration...I thought it was another mistake but now, I think 10x-x=9 is the good mistake in the demonstration Grin

True, you can't exactly subtract infinitesimals from each other.

You're just cancelling out the infintesimally bit. I see nothing wrong with it myself, infinity is too big to think about rationally so whether it's '1' or 'as close as possible to 1' is a matter of opinion.

anyway, 0,999999...=1 is basically wrong^^, because it is a limit, not a bascial equal. Wink

0.999... (also denoted 0.bar{9} or 0.dot{9}) is a recurring decimal which is exactly equal to 1. In other words, the symbols 0.999… and 1 represent the same real number.

Bahahaha, the featured article for today on [link=http://en.wikipedia.org/wiki/Main_Page]Wikipedia[/link] is the article on .999...

Lol, i wanted to do every proof i know over here (digit proof with 0.33333.... *3 = 1/3 * 3, algebraic) in high detail, but you basically answered the whole question :]
