Once i showed that 1+1=1 thing to a math teacher and he totally believed it and stuff.

Kinda like how I proved that you can indeed divide a number by 0, and the outcome is 1. I forget how it goes, it's almost 100% correct, except for one thing, but still.

Basically, it states that if you have X/X the outcome is equal to 1. Also, X/0 is always the same outcome (void). Hence if X = 0, you get 0/0 which must also be 1. However, since all divisions by zero are the same by definition, this means all divisions by zero equal 1.

Only problem is that nobody will buy this, because the first assumption is flawed. It'd be correct to stats X/X where X != 0 equals 1. Oh well, I had a fun half hour doing that again.

Ugh....math...no.

Ahhh!! Too much math...ICKYNESS!!

Back in highschool my teacher would phrase it like this.
x/x=1 for all non-zero values of x.

and of course the non-zero cause-
x/0 is undefined.

Put 0/0 in a calculator, always gives an error.
"Result of function is undefined." -windows calculator

heh

i showed that 2=1 thing to my maths teacher last term

she said "hmm... shall we just scrap it all and start over again?"

it was my science teacher that said it didnt work - but even she couldnt say why. it was the completely wrong reason though.

now i see why it actually doesnt work

lol, someone showed that to my math teacher a while ago, and she sepnt a week trying to figure it out...she finally did though...

lim x->0 (X/X) = 1

This is right. Go Calculus! (I think I did the format correctly, been a while).

.....wait....

Didn't you just limit X to be GREATER than zero? If so, then you didn't prove anything but a number devided by itself is one.

No, I stated as X approaches 0 (from either side) that the value would appear to be 1, even though mathematically the answer is not possible using conventional mathematics. This is true for both positive and negative numbers.

As previously pointed to in these posts... the whole 2=1 equation relies on the mathematical trick that you must divide by zero. Everyone knows that you're not supposed to be able to divide by zero. However, the equation is sneaky. It changes everything into algebraic varibles, so you don't realize you're dividing by zero until you write it all out.

Here is the ellusive equation:

Firstly, let's say that: x = 1

Therefore: x² = x

x² - 1 = x -1

Factorising: (x - 1)(x + 1) = x - 1

Dividing through: x + 1 = 1

Substituting: 2 = 1

So there you have it. You tried to forget about it in 9th grade, and here I go digging up rotting corpses again. All right, I'll put 'em back. Sheesh. Complainers.

Anyway... I had a friend who tried to prove once that 1.999... (insert repeating line) is equal to 2. He basically used logic to account for the fact that it's theoretically impossible for there to be any number in between them, therefore they must be equal. That goes on the logic that between any two points, is an infinite number of points, because a point is infinitely small. Since there can't be a single point between them, they are the same. That ought to throw smart scientist people for a loop... or just get normal people confused about all this inifite garbage. Folks, this is why smart people and crazy people usually end up being one and the same.

My response to what my friend was trying to prove, was that the difference is a theoretical 'infinite carrier'... essentially there is always something slightly missing, even though it is immeasurably small. The missing piece is just stuck up there, being carried over forever.

However, as I've grown older, and into my practicality - I've reallized that dammit, when I'm building a f***ing shelf... 1.999... had damn well better be equal to 2... because I'm not holding the level in one hand, and the tape measure in the other - for another f***ing hour!!!

First, I remember 1.99999 repeating IS equal to 2 based on some mathematical trick that reliably turns repeating decimals into fractions. Unfortunately I dont remember how you did the trick

.

Also, in math is is much easier to use practical examples than numbers. From this I have confirmed that 1/0 is equal to infinity.
Example 1: A black hole (singularity) has a substantial mass and 0 volume. With all that matter sucked into a point of no volume it seems logical to describe it as having infinite density, and thus it has been.
Example 2: One of the reasons for the speed of light being approachable but not attainable is to preserve the law of conservation of energy. If an object moving towards you at the speed of light emmitted electromagnetic radiation, the blueshift would cause the wavelength to be zero, and the frequency infinite, causing the light to carry an infinite amount of energy.

On second thought that 2nd example doesnt prove anything. Its just something I showed to my math teacher when she said she would redeem my points if I found a source to back up my claim that 1/0 was infinite, and that one was in a book on relativity that I read. She still wouldn't give me the points. In fact she was kind of an idiot that didn't really understand the math she was teaching. She got fired in two years.
