Dear Guest  :

 

I have been vaccinated against  CDD  [ Congenital Dumba$$ Disease ]   ....thus, "F'd  Up "  answers don't  trouble me as they would most. However....if you can provide proof of your alcohol consumption - empty bottles, etc.  -  to either Melody or me within 14 days, we will kindly consider your request for 25 bonus points......

 

Sincerely,

The answer is that the limit of 0/0 in the negative directions trends to negative infinity, and in the positive direction trends to positive infinity

 

\(\lim_{x\rightarrow infinity } 0/0=+infinity\)

\(\lim_{x\rightarrow -infinity } 0/0=-infinity\)

 

You can't have a single answer because it depends wheter you aproch it from the negative or positive side

EDIT:

\(x = \lim_{x\rightarrow +0} \frac{1}{x}=+infinity\)

\(x = \lim_{x\rightarrow -0} \frac{1}{x}=-infinity\)

 

Thanks for all the answers! (even the mean ones)
I now realize this is not a actual answer to the question. But it still sheeds a bit of light on why you can't (thecnicaly) divide by cero in linear algebra.


Kudos to CPhill for giving the actual answer

Hi Morianner, welcome to the forum.

 

I am sorry to start you on a negative note but your answer makes no sense.

 

There is no x in your limit !

 

Maybe what you intended to show might make sense.  But what you have shown makes no sense at all.

 

What function is that a graph of?  It looks like xy=c  Where  c is a real positive number. ://

Why is it relevant?

Hi Melody, :D

it is a graph of xy = 1 :D 

Your guess is correct :D:D:D:D

Indeterminate.......to see why.......

 

 a / b  = c  implies that   bc  = a

 

Then

 

0 / 0   implies  that   0   times  [something]  = 0

 

But  "something"  could be  "anything".....thus,  0 / 0   has no fixed value........

 

 

cool cool cool

I am sorry Chris,

I can follow your logic just fine but Morianer's  answer does not make sense.

Yah ... fair enough - I shall give him some points too.

My points are compensation for being so subjected to scrutiny on a first post ...

 

Sorry Morianer :/

It should have been the eleventh commandment:

'Thou shalt not divide by zero'.

Hi Guest #7    

 

Yes there should have been !!

 

Red has just been telling me a story.  

For those of you who do not already know, Red is my pet dinasaur and yes of course he can talk!

 

This is what he said happened to his species.  It is very sad.  sad sad sad

Well, if a moronic dumbshitt  gets 5 points for joining and giving a fucked up answer, I should get at least 25 points for giving a good answer.

 

Melody should get 50 points for having to deal with the personification of stupid ....  well, 25, anyway,

Moronic’s  graph is 1/x

 

CPhill seems immune to personifications of stupid .... he should get 75 points. But only if he shares his immunizing recipe, otherwise -75.  I use alcohol, but it doesn’t work very well. :/

Hi Guest 10,

That is not very polite!

I'll give you 5 points since you offered to give me 50 - even though you imediately took 25 of them away again!  angry

If you signed in, and I expect you already have several available usernames, you could actually give me those points  wink

Good evening Sir CPhill and estemed guest.

 

Tis a question I have also pondered.  How comes it that Sir CPhil is so immune to CDD.

I think tis just thine kind nature that were endowed upon thee at birth.  

But perhaps thee hath a secret, one that not even Her Majesty knows of.

Does The Realm's humble servan have such a immunizing recipe Sir CPhill?

Patented it should be if thine does.....

Sorry, I am not a member so I can’t give points. After using the calculator, I decided to read some of the questions and answers. This is my second visit and that was my first post. I thought it would be deleted quickly, especially posting on your comments with both of you online.  I didn’t expect you to have a sense of humor about it. It is really cool that you do. I reduced the points because the graph is y=1/x instead of xy=c, which is the same thing if c=1. I was just being consistent with the theme of the post. 

 

CDD!  This reminds me of my firm’s principal troubleshooter. He was always looking for a cure or a vaccine for CDD, although he called it Contagious Dumbness Disease.  He would select anyone who f’d up as candidate for experimental trials.  It was a joke, but he often acted as if it was serious.  

 

I have a mostly empty bottle of vodka, a half-empty bottle of gin, and a partly empty bottle of bourbon. These are leftovers from the New Year’s Day party.   I have been draining them but it may be a few weeks or so until they are empty. I probably can’t meet the deadline unless I run into more than the average amount of stupid.  LOL I still have to give a good answer too.

Guest, would you create an account and message me, if you please?  I may very well be acquainted with your “Troubleshooter”
