rossporterlc Posted 24 May 2005 Posted 24 May 2005 0.9999999999 (reocurring) is exactly the same as 1.00000000 (reocurring)
Alexikokopops Posted 24 May 2005 Posted 24 May 2005 explain??? 114166[/snapback] I'd like to help, but I've forgotten. We did about it earlier this year, but I forgot what the lecturerer said, so this is a pretty useless explanation

CasinoGee Posted 24 May 2005 Posted 24 May 2005 How can it be? Maybe if you use a really crap calculator, but in theory it's not.
rossporterlc Posted 24 May 2005 Author Posted 24 May 2005 welll 1/3 is the same as 0.33333 reocurring right? multiply both by 3 then 1 = 0.99999999 reocurring
Alexikokopops Posted 24 May 2005 Posted 24 May 2005 How can it be?Maybe if you use a really crap calculator, but in theory it's not. 114185[/snapback] It's mathematical fact that they are equal. To prove it you have to create a bijection between the closed interval [0,1] and the interval [0,1) and it all works out nicely, proving that 1=0.9 recurring. If I'd written it down I could find it, but I didn't. Edit: Found a different proof for all you non-believers. Enjoy

This is exactly why im going to fail maths
filbertway Posted 24 May 2005 Posted 24 May 2005 mr proof was easier ^^^ 114366[/snapback] WHo's that

Enjoy 114212[/snapback] The dodgy part is the third BIG line. lim x -> endless can make eveything become 0 or endless approximated... something can't be right about it and 1/3 is not EXACTLY equal to 0.3333333 recurring as that is an irrational number It's some time ago now that I had maths, so I might be wrong...

That doesn't go to 0 or infinity, it goes to 1. Aha!!
Knighton Matt Posted 25 May 2005 Posted 25 May 2005 my random fact for the day (if i may ross?) is that there is more salt in a bowl of cornflakes than a packet of ready salted crisps...
Knighton Matt Posted 25 May 2005 Posted 25 May 2005 114585[/snapback] thought it was more interesting than some maths shit! beware newcastle_fox i'm on campus and i'm coming to hunt you down!
Newcastle_Fox Posted 25 May 2005 Posted 25 May 2005 I'm in my house in Jesmond, supposedly revising so dont wanna get disturbed. Good luck for revising for your exams!
