  1. yes, saw that Reminds me of those old HIV-positive blood transfusion cases. IB4 threads turns into a public healthcare thread.
  2. This topic is the math worlds equvilant to the guitar worlds "TOANZ IS IN THE FINGERS, TRUE/FALSE?" question. It's been discussed to DEATH and back, for many many MANY years.
  3. I think what most people here here are missing is the 0.999... part
  4. But the clifs are: statement 1) 0.999... = 1 is true 0.999, 0.9999, 0.99999 != 1, but 0.999... = 1 2) "2 = 1" is false.
  5. Stopped reading here The example I used, was used by our calc professor, on the subjects on proofs (or in this case, INVALID proofs) His whole example went as this: " Example 1.4 We start with: a = 2 We then multiply with A on both sides: a^2 = 2a Subtract 4 from both sides: a^2 - 4 = 2a - 4 apply the Difference of two squares on left side, and factorize out 2 on the right side (a-2)(a+2) = 2(a-2) divide by (a-2) on both sides and get (a+2) =2 but since we started with a = 2 we get 2 + 2 = 2 4 = 2 solution: We've done a couple of formal errors, but the the one that leads to the catastrophic failure is when we divide with (a-2), since (a-2) is (2-2) = 0, which causes Division by Zero. As you see, the whole point was to show division by zero.
  6. There's a whole bunch of examples, pick and choose http://en.wikipedia.org/wiki/Invalid_proof
  7. okay then, set the equation to a = b, instead of a = 2. The whole point was to show that the OP is wrong since his proof is invalid
  8. If a = 2 then a^2 = 4, not 2a. Where the hell do you stoners come up with this? Please stay as far away from college as humanly possible. you multiply both sides with a, you don't square both sides. and the post was to show that 2!=1, since you divide by zero when dividing (a-2) from both sides)
  9. 'nother classic version of the "2=1" with division by zero a = 2 a^2 = 2a a^2 - 4 = 2a-4 (a-2)(a+2) = 2(a-2) (divide both side with (a-2) ) a+2 = 2 2+2 = 2 4=2 2=1
  10. I believe the OP's premise was x = 0.999...(infinite amount of decimals), not x = 0.999, just to get the numbers right.
  11. dude, next time you go amp shopping, hand the seller a 1$ and show him with mathematical induction that if 1$=2$, then 2$=3$ etc, so that your 1$ bill = whatever amount he's asking.
  12. Most Yngwie clones claim that they're "Blackmore inspired".
