Thank you, I am glad we finally agree that you cannot do math with letters.

So we agree that 0.(9) = 1?

Do you agree we can't do math with letters?
Yet letters are functioning abreviators, you cannot accurately display matematics without them ;)

Only in the sense that any letters used in mathematics must represent numbers, operations, sets, matrices or other mathematical constructs.

Very well, only in the sense that there is an error between 0.999... and 1.0 but it is infinitely small.

Then I ask you again; what is a number that is between 0.999... and 1?

There isn't one.  .999... is the last number before 1.0

If the difference between 0.999... and 1 is infinitely small, it is 0.

1 - 0.999... = 0

Thus, 1 = 0.999...

Yes, thanks to the tireless efforts of Euclid and a few other mathematically-inclined members, electromagnetic acceleration is fast moving into the forefront of FE research.

What is (0.5 * 0.999...) + (0.5 * 1.0), that is to say, the mean of 0.999... and 1.0?

I have already conceded on this point.


The real win here was my entire win against everyone on the board, in the letters and math debate.

1/3rd of 1 cannot be properly represented in numerical form much like π (pi) so recoupling a numerical representation of 1/3rd of 1 (0.33333 X 3) will never be 1 due to the loss in rounding down upon the initial division.

Seriously? I just spent an entire week in math, doing it without any numbers, you need to understand the algebra in order to do math, and algebra is math with letters.

No Algebra is math with letters that stand for numbers.  Therefore you can't do math with letters.

And as I said, I just spent an entire week doing math with nothing but letters. You can do math with letters.

No you can't.  Show a math problem that can be solved without having to replace the letters with numbers.

It's simple enough, x=h/a. See, no numbers needed.

That doesn't solve the actual equation.  I say that x cannot equal a divided by h.  Prove me wrong.

It's basic math that provides a basic knowledge, if you learn this way first, it makes solving it when the numbers come in much easier, just a few quick calculations. In a way though, I guess I can see where you coming from, or maybe I'm just that tired, I don't know anymore. :'(

well since originally ax=h


either a or x =h.

Then the solution DNE, but you still solved for x, the answer was just unreal.

No, because in order to solve for x (which you did wrong, by the way, it should be h/a, not a/h, so instead suppose that a=0), you would need to divide both sides of the equation by zero, which violates the laws of mathematics. The equation x = h/a would be valid only when |a|>0.

I can agree with that, and good catch on the original equation, I'll edit it eventually. I should probably get some sleep too.

So when you said you'd disproved my sig in this thread, what you actually meant was you'd decided you'd completely failed and just thought you'd drag me back in to tell you again?  Well, ok, if that's what floats your boat...

x = a/h was defined.  If you don't believe that it's the correct definition, then fine, you can do what you were talking about and test it with numbers. If the relationship was arrived at through pure theoretical derivation, however, that doesn't make it invalid.  Maybe x = a/h is the result of a proof that cannot be refuted theoretically.  It's still maths.  You're confusing pure maths with applied maths, or maths with physics.  You're also confusing proving me wrong with being an utter failure.
