(In reply to re(3): alternate proof by Tristan)

Tristan, you wrote:
No one seems to have thought of this proof...
Now you write:
Tom already addressed this in one of his replies.

So either:

  • Tom *has* already thought of this proof, or
  • You are relying on his work to complete your proof, but failed to mention it.

    *I* don't think your proof is at all valid (although I do agree with the conclusion, that .39999... = 4), and we both agree that it isn't rigorous.

    Therefore, and since I am quite comfortable with the accepted proof, I will not attempt to improve upon yours.... Perhaps someone else will.

    Cheers!
