So whare's the mistake Mr. Wise Guy

yeah, you are probably right.

Joke? Maybe I don't know something ?! But I hope you're not talking about lim x->0 .

Division by zero is not possible in COMMON sense

As I said before, there will be no winner until I'm an admin :> lol

BTW: My classes start in next week, so I'll probably write not so often

Well, yes, the transformation is wrong
:D
One can easily generalize sqrt() to complex numbers
I agree.

The problem with the "equation" above is that no possible generalization is reasonable enough to be distributive w.r.t. multiplication anymore.

In other words it is the same what I said :P ...

Nope. We define i to be a "number" such that i*i = -1. By adding i to the set of all real numbers and closing it under addition and multiplication we get the complex numbers -- all numbers of the form a+bi. For example, (7i)^2 = -49, (3+i) * (2-i) = (6 - 3i + 2i - i^2) = 7-i, etc.

Man, I have ...

As far as I remember the domain of function of square root is {x in R, x >= 0 }. So you can not write "sqrt(-1)". Error is in transformation "sqrt( (-1) * (-1) ) = sqrt(-1) * sqrt(-1)".

Lets see a proof:
Let,
a = b
=>a^2 = ba // multiplying 'a' on both side
=>a^2 - b^2 = ba - b^2 // adding -b^2 on b.s
=>(a + b) (a - b) = b (a - b)
=>(a + b) = b //dividing by (a - b) from both side
=> 2b = b // as a = b
=> 2 = 1 // ?? :o

Yeah, but not only me. You shouldn't post too

The answer is: "Poland lies in Central Europe" It's great there's so many good answers

We have no affect on this game. It will probably run until someone closes this forum. And this won

That's a long time. Maybe it's never ending story

What veterans? Does this game run for couple of years ?!
