## anonymous 3 years ago Infinite/Infinite=?

1. TuringTest

infinity is not a number, so you are basically asking "what is purple/purple ?"

2. anonymous

u cant define an infinity... so infinite/ infinite cant be defined....

3. anonymous

purple and purple is probably equal to a darker purple

4. TuringTest

I don't know about that, I've never tried to divide purple ;)

5. anonymous

i just wanna see all of your thoughts on this problem

6. anonymous

infinite is not a rational number so cannot be divided.

7. anonymous

thats undefined just like 1/0

8. experimentX

|dw:1349360636661:dw| now if you allow this whole number system will collapse. These are called indeterminate forms and you do your best to avoid these things. http://en.wikipedia.org/wiki/Indeterminate_form

9. anonymous

its an undefine case because any number divide by infinity = zero and infinity divide by any number is = infinity so here you cannot consider any of these case separetly so its undefine case

10. anonymous

if you have given limx-->infinity then 1/infinity=0

11. anonymous

undefined?? but is it possible to solve?

12. anonymous

nope not possible but can be in limits.

13. anonymous

L'HOPITAL'S RULE!!!!!

14. anonymous

yes thats in limits.

15. TuringTest

L'hospital is only for limits of functions there is no function in infty/infty

16. experimentX

yeah there are few cases where you can solve this kind of stuff ... but you better come up with problems where you encounter it ... it would be concrete.

17. TuringTest

to show you the problem with your idea${\infty\over\infty}={\infty+1\over\infty}={\infty^2\over\infty}$now, are they any different?

18. anonymous

what chapter of your text are you in? is this for limits or improper integrals? or something else?

19. TuringTest

how could they all have the same solution, and if so what would it be?

20. TuringTest

If you want to go really deep down the rabbit hole, learn about hyperreal numbers http://en.wikipedia.org/wiki/Hyperreal_number

21. anonymous

Im studying trigonometry, i dont know what that limits mean and i just recently researched that L'Hospital rule i didnt even understand a thing 8-I

22. TuringTest

or Cantor's set theory

23. TuringTest

forget l'hospital, you'll get there when you take calculus

24. anonymous

pre calculus?

25. anonymous

i wonder if "/" is defined for so called infinity........... infi is representation of a v.large number.........it doesnt say how large and if it is defined.....say it somethin like a v.l num/ a v.l deno so denom can be <= num so it can be anythin so........the qn is not complete...... :P r is it's jus a troll

26. TuringTest

maybe, but l'hospital involves taking the derivative, and derivatives are a part of calc, not precalc sometimes they try to throw it into precalc it is hard to understand l'hospital without understanding the derivative

27. anonymous

limits are in pre calculus but i havent encountered that hospital rule

28. anonymous

i see

29. anonymous

im closing this question thatbks guys

30. TuringTest

welcome always fun to talk about infity :)

31. TuringTest

even if I can't spell it :P
