if we divide y on each side then we get 2...y is 0. <br />if we divide y on each side then we get 2=1 <br />but this is inconsistent with the real numbers and it is a contracdiction to the fact. <br />thus we conclude that x=y=0.<br />I think we call this prof by contracdiction in mathematics. we use this technique to show the hypithesis we made is wrong.Mansfieldnoreply@blogger.comtag:blogger.com,1999:blog-4010478591191633760.post-48714742960297092992011-04-30T09:25:39.553-07:002011-04-30T09:25:39.553-07:00Charles Mak's brother,

And no matter how you rotate the square, its area would be the same. That's mean that there is loss in information (that of direction) in the process.<br />The notion 1=-1 is not "untrue", but it is "not the whole story of the truth" by eliminating the information on direction.rsericnoreply@blogger.comtag:blogger.com,1999:blog-4010478591191633760.post-61913215313220858752011-04-29T21:07:08.571-07:002011-04-29T21:07:08.571-07:00看來這對大家來說太容易了,我不一一回應喇!看來這對大家來說太容易了,我不一一回應喇!W.

任何數除"0"...我估應該要考究一下點解任何數都唔可以除"0"<br />任何數除"0"為何定義為indefinite?<br /><br />如果任何數除"0"係definite,咁樣即是 0/0 = 1<br />咁會好大件事...<br />e.g.<br />0 * (x + y - 123) = 0 * (x - y -456)<br />唔知自己計緊乜,哈哈...<br /><br />總之若果 x = y,計到要除(x - y)的時候已經產生邏輯不合法的情況,因為(x - y)一定會係"0"<br /><br />至於問題本身,其實可以著重於任何數除"0"為何定義為indefinite?Galileo Chttp://blog.qooza.hk/galileostorynoreply@blogger.comtag:blogger.com,1999:blog-4010478591191633760.post-36112262688731096762011-04-29T07:57:44.854-07:002011-04-29T07:57:44.854-07:00hehe :)
