f(x)=1/(1-x)

if i start at 0.9 and then I keep adding nines to the end of it at what point does the function become undefined?

Well, f(x) is going to be in the reals no matter how many 9s you add. But f(1) is not a real.

So are you arguing that f(0.999...) != f(1)? Whose side are you on anyways?

f(x) = 1 / (x0 - 1)

If I start at f(0.9) and keep adding nines to the end at what point does the function become undefined?

f(1) is approaching zero.

As x nears one,

F(x) approaches zero.

F(1) is zero.

F(1) is zero.

f(x) = 1/(1-x)
then f(1) = 1/(1-1) = 1/0

So now in addition to 0.999... = 1 you're also claiming that 1/0 = 0??

This thread just keeps getting weirder and weirder...

I said that?

No I didn't. Google what limits are.

Take calculus.

Well, Robosteve is using all the shiny calculus a few posts up, and he doesn't seem to be getting f(1) = 0

Why can't you REers just admit when you're wrong? Instead of clinging onto hopelessly indefensible positions such as 1/0=0?

1/0 equals undefined. we don't know what it equals.

Then how can f(1) equal zero?

It's because as x gets close to 0+, f(x) gets larger and larger. So we can write it as ...999999.0 which is the same as 0 when you have an infinite number of nines.

This thread has become the highlight of my day. I wish it had been around when I was in grad school.

Ok, lol i checked this thread while not drunk finally. Lol. It is (infinity symbol). My bad. I didn't realize it was approaching infinity.

(1/3)+((1/3)/3)=10

So to me 9.9999.. does not equal 10

(1/3) / 3 = (1/9)

(1/3) + (1/9) = (4/9)

You fail.

Enter this into any calculator

(1/3) + ((1/3)/3)

You will get 0.444...
