Yes, 0.999999999............... does equal 1.
Let's use a simple algebraeic equation.
Let c = 0.999...
10c= 9.9999.....
10c -c = 9
9c/9 = 1.
c = c
1 = 0.999... |
If you knew the answer what was the point of this thread...
|
Wrong again, once you multiply c *10, theoretically at the end of the infinite 9's there would be a zero. Which is why 9.... or 9-bar is not .9999999 infinite, it's a symbol for a number that can't be expressed in decimal terms.

Theoretically, if infinity has no end, how is there zero at the end of it?
|
i still don't see how people are convinced they can calculate with infinity |
It is easy. What is infity minus infinity? Zero! What is Infity times one infityth? One! Or alternatively, what is infinty divided by infity? One! What is infinity times 1? Infinty!

Infinity isn't a number.
@happy, we basically agree then. But I conclude that infinite repitition is imprecise, and you can not.
.3-bar ~= 1/3
so .9-bar ~= 1
If your going to use calc constants then you may as well say that dividing by zero can be graphed in real numbers.
Calc makes the intangible, managable.
