Guest Zeh Posted November 12, 2001 Posted November 12, 2001 My older brother just sent me an e-mail.... He thinks that math is a lie... look at his work do you agree? [QUOTE] Given (1) X = Y Multiply both sides by X (2) X^2 = XY Subtract Y^2 from both sides (3) X^2 - Y^2 = XY - Y^2 Factor both sides (4) (X+Y)(X-Y) = Y(X-Y) Cancel out common factors (5) (X+Y) = Y Substitute in from line (1) (6) Y+Y = Y Collect the Y's (7) 2Y = Y Divide both sides by Y (8) 2 = 1 This is why Math as we know it is a lie. This also proves I have way too much free time.....maybe thats a good thing or maybe it's not...its too early to tell. Cheers Dan the toooooo much free time man [/quote]
mornigndew Posted November 12, 2001 Posted November 12, 2001 [color=blue] Yes, this is false. There's a flaw in it.Given [/color] (1) X = Y Multiply both sides by X (2) X^2 = XY Subtract Y^2 from both sides (3) X^2 - Y^2 = XY - Y^2 Factor both sides (4) (X+Y)(X-Y) = Y(X-Y) [color=blue] (x+y)=y(x-y) ----->(1+1)=1(1-1)--------->2=0. You cannot divide zero, it's undefine. If you're know what I mean. Someone probably have a better explaination, I can't explain it on the computer. [/color] Cancel out common factors (5) (X+Y) = Y Substitute in from line (1) (6) Y+Y = Y Collect the Y's (7) 2Y = Y Divide both sides by Y (8) 2 = 1
Guest Zeh Posted November 12, 2001 Posted November 12, 2001 Good work But if you keep letters only and odont substitute in till the end it still works and if we used calculus on it we get 0=1 :babble:

Guest Dark Man X Posted November 12, 2001 Posted November 12, 2001 I hate math! I used to be so good at it. I think that that problem was just a problem with no solution. There [i]are[/i] such problems like that.
Guest Voodookanaka Posted November 12, 2001 Posted November 12, 2001 Theres no justified reason behind Y=X in the first place. I mean....just because you rearrange it for a long time it still doesnt change the fact that 1=1 2=2 and that for X and Y both can be C.r.v. At the end if u -1Y from each side u get: Y=0 whic sums up the whole equation.
Cecil Posted November 12, 2001 Posted November 12, 2001 He probably made this up in his head. It might be right or it might not. It looks right to me though. Although I think there is something wrong with 4. Everything before this was before I read moriningdews post.

Cecil Posted November 12, 2001 Posted November 12, 2001 You right mornigndew, he didn't make it up in his head. He made it up using his head and a pencil and a sheat of paper (or a computer).

masterfork Posted November 12, 2001 Posted November 12, 2001 Um... after a certain point, there would be no reason to continue, and that point is right there... Given (1) X = Y Multiply both sides by X (2) X^2 = XY Subtract Y^2 from both sides (3) X^2 - Y^2 = XY - Y^2 ------ [b]LOOK: if they equaled each other, X^2 - Y^2 would equal 0, and the same for the other side. Therefore you would have no reason to continue past this point.[/b] Factor both sides (4) (X+Y)(X-Y) = Y(X-Y) Cancel out common factors (5) (X+Y) = Y Substitute in from line (1) (6) Y+Y = Y Collect the Y's (7) 2Y = Y Divide both sides by Y (8) 2 = 1 [edit] I just saw something else. I don't see how (X+Y)(X-Y) would equal X^2 - Y^2... That makes no sense either.
Zidargh Posted November 12, 2001 Posted November 12, 2001 Um, I hate Science. And math is a lie it has been clinically proven by my point of view. Not many people notice this but the computers stick in trick questions which we don't realise... Oh well, it never get in our heads anyway it just kinda comes in then out, but for some reason I'm pretty good at it. (Dont mean to sound Big Headed)
Defcon5 Posted November 12, 2001 Posted November 12, 2001 why in gods name would someone need to know how to do that?
Fall Posted November 12, 2001 Posted November 12, 2001 You don't.............. Anyway, I hate all kinds of Maths, and I'm good at it for some kind of reason.........???
Wild Freedom Posted November 12, 2001 Posted November 12, 2001 ive seen this problem before. I showed it to my algebra teacher and she retired that year. Coincidence?....I think not!
Pressure Posted November 12, 2001 Posted November 12, 2001 [COLOR=purple]um... I uh.. ehhh *whines*[/COLOR] [COLOR=green]um, Alice and I got lost on step ... 2... [/COLOR] [COLOR=purple]shaddap... i did not! it was step 3!!!![/COLOR] [COLOR=green]my bad[/COLOR] [COLOR=purple]genius[/COLOR] [COLOR=green]anyways..[/COLOR] [COLOR=purple]right.. oh yeah, um, I Do Swear, That In My Career As A Professional Actress, I Will Never Need To Figure Out X=Y[/COLOR] [COLOR=green]that was beautiful[/COLOR] [COLOR=purple]thank you[/COLOR]
Transtic Nerve Posted November 13, 2001 Posted November 13, 2001 Math is not a lie.... most people who try to proove it just don't know how to do it.. there are Math laws you know... math works... 100%.... only if you follow the laws... it's like... the Pythagorean Theorm only works with right triangles... thus that is a law.... alot of math is undefined simply because it cannot be done, like the above.... math is not a lie, simply done incorrectly :p Sorry if I sounded mean or rude, It wasn't meant to be.
Sara Posted November 13, 2001 Posted November 13, 2001 [QUOTE][i]Originally posted by Transtic Nerve [/i] [B]it's like... the Pythagorean Theorm only works with right triangles... thus that is a law...[/B][/QUOTE][FONT=century gothic]My teacher once told me that if anyone I knew mentioned the Pythagorean Theorem outside of class, he'd give me a dollar.... Too bad I don't go to that school anymore...[/FONT] :p
GinnyLyn Posted November 13, 2001 Posted November 13, 2001 By the way: a^2 + b^2 = c^2 *eyes Cera's last post* Wanna go halfsies? My mom and I complain about that theorem all the time. And if [i]anyone[/i] tries to tell me that math is FUN, that it is freaking GOOD FOR YOU, then you can KISS M-- kiss my gerbil, uh yeah, that's what I meant.

She refuses to use the F word...so she replaces it with "freaking" in about every sentence that comes out of her mouth. Hehe...the resemblance is remarkable...[/color]
Fall Posted November 13, 2001 Posted November 13, 2001 Nobody needs too know maths. You don't need it to live, unless you want a good job, which I do.So I will be learning maths............... And that's that!
