Prove It


Recommended Posts

Right...

Well, there can be another method-

0/0=1^2-1^2/1-1=(1+1)(1-1)/1-1=2

 

There is so much so wrong with this.

 

For the record: 1² - 1²/1 - 1 = -1

So you say 0/0 = -1

Which is very obviously false and since you have not proven this in a lemma before, it is incorrect to use this in your proof.

 

You seem to have a little problem using parentheses.

You also state that (1+1)(1-1)/1-1 = 2

 

Let's continue with what it says: (1+1)(1-1)/1 - 1 = 2

2 * 0/1 - 1 = 2

-1 = 2

Obviously false.

 

Let's continue with what I think you mean:

(1+1)(1-1)/(1-1) = 2

(1+1)(0)/(0) = 2

2 * 0/0 = 2

Which you cannot use since you try to prove that 0/0 = 2, and now it states that 2 * 0/0 = 2. Such thing can never be true. As stated before, 0/0 is undefined and will never be.

0/0 can be anything.

like:

0*2 = 0

i.e: 0/0 = 2.

 

Now:

0*x = 0 or 0/0 = X, where x can take any damn value. :)

 

I'm not convinced that that is true. But I generally don't feel the need to go into discussion with someone from India when it comes to maths.
