EPT1/3 = 0.333...
0.333 * 3 = 0.999...
1/3 * 3 = 1.
... or you could just have gone to the wiki page for it.

So this is clearly a matter of infinite numbers. You can make all sorts of approximations that way. Just look at things like infite x infinite = infinite. Also, infinite x 1 = infinite. So does that mean that 1 = infinite? No. It's just that you're working with numbers that are too large to comprehand. 0.999 has that 9 repeated a whole lot of number of times. So even if it's not 1, it's pretty goddamn close. So a 0.999... = 1 convention is not outrageous as saying 9=10. It's just one of those cute things like 0 x infinite = impossible. Because normally it would be 0, but the infinite is SO BIG, that it should be something (lol, gotta love maths), or infinite / infinite, 1 at the infiniteth power, etc. I like to say infinite. | ||

First we will set up the infinite series to deal with this: โ E (.9)(.1)^k k=0 This means we have .9 + .09 + .009 onto infinity, or .9999.... This is also a geometric series with r=.1 and a=.9. The sum of an infinite geometric series is a/(1-r) So .9/(1-.1)= .9/.9= 1 Trust me, I've done this a thousand times in class. .9999999... DOES equal 1. | ||

THe problem is you can't just do an infinite sum with just 9...because then it is just...9... Geometric series are usually used to show how to represent certain numbers as fractions like 1.345345345.....they can all be done using infinite series. | ||

Or maybe Blackthorne 2 or RPM Racing 2. And blizzard is a hype machine. Do any of you think it's possible to find out what the answer is (like a notpron puzzle or something)? | ||

Geometric series alone, I suppose, could be taught without calculus, but you won't find it in a class alone like that...you will probably find it in a Cal II or III class. It is considered calculus material due to its relation to infinity and limits. Reimann sums... | ||

But according to algebra it's a "special case", or an impossible scenario (i don't know what the exact translation is), and the expression that contains this scenario will have to be modified in order to solve it. As I said, there are different things that can't be sovled like 1 at the infinith power, or infinite devided by infinite. Multiplying 0 with infinite is about the same thing as trying to devide by 0. Sounds simple, but it can't be done. Of course, you're working with theoretical numbers, so don't expect them to obey the standard rules. We in Romania learned about these (limits, derivation, integration - i sure hope that's an accurate translation) in high-scool, and then moved on to more complicated things like the Reinmann sums in colege. So you could know about limits and such without learning calculus.  | ||
