Adakah ni nak tahu sapa pemenang world cup 2006? 1962, 1970, 1974, 1978 tu semua tahun world cup berlangsung...
Kalau ni la jawapannya, mana ada kaitan ngan sains ngan math.... |

Di samping anda melihat gambar-gambar mustahil.... Tolong bincangkan ini...
katakan x= 0.99999999999999999999999999999 (infiniti)
so, 10x=9.99999999999999999999999999 (infiniti)
lalu 10x-x=9
x(10-1)=9
9x=9
x=1 (???? :kant: ) |

kan senang kalo bulat kan aje 0.9999999999999(infiniti) tu sbg 1

Hello aku_EnSeM 
Lama tak nampak. Dah start belajar ke? Utk menjawab soalan di atas.
When you think of 0.999... as being 'a little below 1', it's because
in your mind, you've stopped expanding it; that is, instead of
0.999999...
you're _really_ thinking of
0.999...999
which is not the same thing. You're absolutely right that 0.999...999
is a little below 1, but 0.999999... doesn't fall short of 1 _until_
you stop expanding it. But you never stop expanding it, so it never
falls short of 1.
Suppose someone gives you $1000, but says: "Now, don't spend it all,
because I'm going to go off and find the largest integer, and after I
find it I'm going to want you to give me $1 back." How much money has
he really given you?
On the one hand, you might say: "He's given me $999, because he's
going to come back later and get $1."
But on the other hand, you might say: "He's given me $1000, because
he's _never_ going to come back!"
It's only when you realize that in this instance, 'later' is the same
as 'never', that you can see that you get to keep the whole $1000. In
the same way, it's only when you really understand that the expansion
of 0.999999... _never_ ends that you realize that it's not really 'a
little below 1' at all.

yg mana betul?
10x-x=9
atau 10x-x=9x? |

Sebenarnya dua-dua betul.
Bagi yang pertama:
10x - x = ?
x = 0.9999....(infiniti)
= 10*(0.9999....) - 0.9999....
= 9.9999.... - 0.9999....
= 9 |

very good explanation.. i've been thinking of this matter for almost 1 week since i received this problem.
when i tried the same concept to the other number, different thing happens..
x=0.88888888888888.........
10x=8.888888888888888888.......
10x-x=8
9x=8
x=0.8888888888888........ |

Good observation. Tak pernah terbaca pasal nombor bertitik perpuluhan infiniti lain selain 0.9999.... lagi

Boleh ke kita anggap 0.99999....... = 1?
if 1 / 3 = 0.33333333333333.............. then
0.333333333333....... x 3 not equals to 1.
haduih, penin2 |
