Is 1 = 0.9999......

Dude, I knew that he probably found out his mistake, that's why he never published it..... but he didn't publish a lot of other things too..... Nonetheless, it was intimiating for the rest of the mathematicians (a lot of them French) to find in one of his personal notes, after Fermat died, that...

Is 1 = 0.9999......

ah.... I think I see what's the big deal is, no one has ever found the fraction that define/create 0.99999......., huh? oh well, mankind would eventually find it..... someday. Just like Fermat's Last Theorem.... took humanity more than 300 years to prove it, while this guy Fermat just say it's...

Is 1 = 0.9999......

Really? magna cum laude? Me, too, I missed summa cum laude by like 0.03 or something like that. :( But mine is not applied math, it's abstract math. P.S. are you sure about you learning this in class?

Actually, to be the "Devil's Advocate" and confuse people more, 1/9 = 0.111111........ 9 * (1/9) = 9 * (0.111111.........) hehehe, the rest is more fun for you to figure out yourself. (I am surprise no one mention this one, just keep mentioning the one "proof" in the original post).

No, I am stating that for all purpose of Applied Math, 0.99999..... = 1. But strictly speaking, like in number theory or abstract algebra, 0.99999.... != 1.

I think what he meant was that 9.99999.... - 0.99999..... != 9. Because if you substitute x = 0.99999......., then you get 9.99999........ - 0.99999....... = 10x - x = 9x , not 9

Actually, it is yes and no, depending on which field of math you are talking about. If you are talking about Applied Math (for science or engineering), it is yes, 0.99999... = 1 (it is close enough.....). However, if you are talking about Abstract Algebra or Number Theory, then no. The reason...

Need Help choosing External CDRW Drives

Hi, I need help deciding between Cendyne 48x12x48x USB2 burner and the I/O Magic 52x24x52x USB2 burner. The Cendyne will be on sale at OfficeMax for $80 - $30MIR = $50, while the I/O Magic burner is $83 at Office Depot (no rebate). I heard that the Cendyne one is a Lite-On drive, and the...

Need Some Math Help

Yes, finally a math question that is close to Algebra..... To TheEvil1: I think DeafeningSilence has the definitions of injective and surjective cross-wired. Anyway, onto answering your question..... for injectiveness, the answer would be "No", as shown in the example by DeafeningSilence...
