I don't remeber any Parabolic formula. What math so they talk about that in?

 

Re: 0

Calculus 2. LOL

 

Re: 0

OH. I am in Calc one because the idiots at my school lost the records of which math classes I took when and what grade I got.

 

Re: 0

How is that right? 0/1 = 0 and 1/0 = undefined
0 = undefined??

 

Re: 0

0/0 is undefined, at least as far as computer science is concerned, it's usually represented by NaN

 

Re: 0

No... 0/1 = 0 because it is a non-quantity being divided into one category. Can't be done, so the answer is 0. 0 in 0 categories. Just because you divide it up doesn't make it equal anything else.

1/0 is the same... 0. It's only "undefined" because a quantity can't be put into a non-existent number of categories. So while your calculator tells you it's undefined, and it can be classified as that, the quantitative answer is still 0.

 

Re: 0

This is even crazier than my math teacher saying .9 repeating equals 1.

Weeee...another mathematical question to unravel

 

Re: 0

[me=Meee]is not a Wizard [/me]

btw. does 0 belong to N or not?

 

Re: 0

Your math teacher said that?

For all practical purposes it can equal 1. But it doesn't equal 1.

 

Re: 0

I know why that is.

.3 repeating is 1/3=3/9 .4 repeating is 4/9. this is because any number repeating is that number over 9 so .9 repeating =9/9=1

 

Re: 0

lol, I think I was the only one he never convinced that it was true. All the other students just accepted it without much arguement. His proff was that no number exists between .9 repeated and 1, there for they are the same.

More proff

1/9 = .1 repeated
8/9 = .8 repeated
.8 repeated + .1 repeated = .9 repeated

but 1/9 + 8/9 = 9/9 = 1

thus .9 repeated = 1

 

Re: 0

0/x = 0 is perfectly defined because 0*x = 0

x/0 does not equal to 0 as 0*0 does not equal to x, in fact 0*x=0 for any number so there doesn't exist a number y such that 0*y != 0, therefore x/0 is undefined, but people usual use +/- infinity to represent this

0/0 is the opposite x/0, the solution could be any number, where as the solution for x/0 couldn't be any number.

 

Re: 0

I'm confused! All this math stuff should stay in the classroom. Just reading this makes me tired, but its too fun to see ppl legally arguing, participating makes it even more fun.

still say 0/0 equals 1 but I'm not sure if that right anymore.....

 

Re: 0

It can't be one! Just think of it rationally, not mathematically.
So I have no cookies, which is 0 cookies. Now I give them to no people. What happens? I get free cookie? No, I don't.

 

Re: 0

See what you did BirdofPrey!!! You made everyone doubt the one thing that's always supposed to stay the same

 

Re: 0

Makes sense, thus 0/0 = zero! finally something that works.

 

Re: 0

Well, duh. It only works in your crippled real world. In MY world with magic I'd get a cookie. I feel soo robbed...

Re: 0

x/0 is like
__
\/ -1 because it can be defined as a imaginary number even though such a number can't possibly exist.

the answer to 0/0 does exist, but there are infinitely many of them, every number is a solution to 0/0 that's why it's truly undefined, because to be defined something has to have a definite meaning, hence the term defined. 0/0 doesn't have a definite meaning, you can't even use a imaginary number similar to i becuase it would have to equal every other number. where as i is well defined to be the square root of -1
