Guest smoggeordie Posted October 30, 2006 Share Posted October 30, 2006 DO NOT RUIN THIS IF YOU HAVE STUDIED MATHS Theorem: 3=4 Proof: Assume: a + b = c This can also be written as: 4a - 3a + 4b - 3b = 4c - 3c After reorganising: 4a + 4b - 4c = 3a + 3b - 3c Take the constants out of the brackets: 4 * (a+b-c) = 3 * (a+b-c) Remove the same term left and right: 4 = 3 How is this possible?

Guest smoggeordie Posted October 31, 2006 Share Posted October 31, 2006 Do your own homework. haha, i've already finished my six assignments for this week. Mainly on the poisson process, maximum likelihood estimates, graph theory, chaos theory, Transformations of random variables, the Cramér-Rao inequality etc.....

Dr Spectrum Posted October 31, 2006 Share Posted October 31, 2006 10x=9.9999999999999999999999999999 I don't agree with this. You can't mess around with an infinite number of 9s like that nono.gif You can't use Algebra to proove things that are blatantly false. 4 will never equal 3 just the same as .9.. will never equal 1.

Guest smoggeordie Posted October 31, 2006 Share Posted October 31, 2006 Example Convert 0.142857142857... into a fraction. Let x = 0.142857142857... We want to move the decimal point to the right, so that the first "block" of repeated digits appears before the decimal point. Remember that multiplying by 10 moves the decimal point 1 position to the right. So in this example, we need to move the decimal point 6 places to the right (so we multiply both sides by 1 000 000): 1000000x = 142857.142857142857... Now we can subtract our original number, x, from both sides to get rid of everything after the decimal point on the right: 1000000x - x = 142857 So 999999x = 142857 x = 142857/999999 = 1/7 http://www.mathsrevision.net/gcse/pages.php?page=8 Link to post Share on other sites More sharing options...

Yorkie Posted October 31, 2006 Share Posted October 31, 2006 For when people are done with whatever one you're on... I was doing a maths paper this week (GCSE practise) and ended up with this bastard of a question that i couldn't make head nor tails out of. 5a + 3b = 9 2a - 3b = 12 What is a? What is b? I kinda worked out that 'b' must be a minece but got nowhere. Anyhow, resulted in me losing the three marks and a rollocking from the teacher. Stupid fat bitch didn't tell me how i should have done it, just pulled the paper away from me and told me to sit down. Great! So, when you're done people, if you will ^^^ . :wink: Link to post Share on other sites More sharing options...
Dr Spectrum Posted October 31, 2006 Share Posted October 31, 2006 But the number .9999.... doesn't really exist. An infinite number of 9s? Infinity does not exist in any real sense of the word, its just a philosophical concept. I don't see how you can just pick up a dot and drop it one place further along a line when the distance between this said dot in relation to the right hand edge of this line (The one way over there ~~~~~~~~~~~~~~~~~~~>) is immeasurable. Its too simplistic. Maths is a load of shite. Link to post Share on other sites More sharing options...
