Does it? proof please?
How infinitely many elements can have a sum?0.999... is DEFINED AS the sum of the geometric series...
Sigh, no it is the limit of n approaching infinity. It never actually reaches infinity just as you can never write 0.999... out in full. This is barely above high school mathematics and really simple to understand if you read it and tried to learn something.Organic said:How infinitely many elements can have a sum?
All we can say is that they are approaching the sum, but never reaching the sum.
Shortly speaking, this is the all idea of being infinitely many ... .
Standard Math breaking its own rules by saying that .999... = 1

Demonstrate a zero gap between 0.999... and 1if you do not believe that 0.999... = 1, it should be very easy for you to prove it. find a real number between them.

pig said:don't you agree that for every non-zero real x, it is correct that: |1 - 0.999...| < |x| ?
since by substracting 0.999... from 1 we get infinitely many 0s after the decimal point, the result is smaller than any number which has a non-zero digit.
unless you consider things which make no sense like "0.000...0001" real numbers.
and that leaves zero as the only possible solution in R.
Organic said:Sure Chroot, it is closed exactly like Lord kelvin once said about Physics, and then Plank came ...
"Proof that .99~ = 1" is a mathematical concept that states that the repeating decimal 0.999... is equal to the whole number 1.
Yes, there is a formal proof for this concept. It involves using the properties of limits and infinite series to show that the decimal 0.999... is equal to the limit of the infinite series 0.9 + 0.09 + 0.009 + ... which is equal to 1.
It is important to know this concept because it helps us understand the properties of real numbers and the concept of infinity. It also has practical applications in fields such as calculus and computer science.
Yes, this concept is universally accepted by mathematicians and is considered a fundamental property of real numbers. It has been proven by many mathematicians and is supported by countless mathematical examples and proofs.
One common misconception is that 0.999... is not equal to 1, but rather infinitesimally close to 1. However, as the formal proof shows, 0.999... is indeed equal to 1 and not just an approximation. Another misconception is that this concept only applies to the decimal system, but it actually applies to all base systems, as long as there is a repeating decimal representation for the number.
