What thread? A link would be nice if possible.

Also, what does it say? I don't want to download that whatever math thing b/c my comp is slow enough as it is. - 04-20-2002ygfperson
i've downloaded the math thing, and it doesn't seem bulky. (then again, in windows...)

here's basically what it says:

where E is the weird symbol for infinty and stuff... i haven't taken calculus so i don't know what its name is

Proof that 0.9 recurring equals 1

1-.9 = 10 ^ -1

1-.99 = 10 ^ -2

1 - .99999 = 10 ^-5

Code:

x

1 - E (9 x 10 ^ -x) = 10 ^ -x

i=1

Code:`lim x->infinity {10 ^ -x } = 1/(ln 10) * lim x->infinity { e^-x} = 0`

x

therefore lim x-> infinity { 1- E (9 x 10 ^ -i)} = 0

i=1
