ada kes yang garis selari bertemu dan segi tiga lebih dari 180 degrees

example.........
kamu berada di tepi saya dan berjalan....... direction kami selari kan?? kamu tak akan langgar  ...

test this I think..

even newton couldn't answer this question and the interesting part is, he had a value of IQ of 190!!!

3 / 2 has no logical solution, so human devises the concept of fraction.
5 - 10 has no logical solution, thus human introduces the concept of negative number.
Even more radical, surd -1 has no solution, so mathematicians introduce concept of the imaginary number
1/0 has no solution, so mathematicians use infinity....

how much is 1.5?
how much is -5?
how much is i?
and how much is infinity?

just want to check, why
1/0 = infinity?
1/infinity = zero?

for ex, saya ada satu keping roti, nak bahagi 0 orang? so, kenapa mesti infiniti?
even saya ada sekeping roti, tp bahagi berjuta2 lemon.. nilainya akan mendekati 0?
tp blum 0 lagi, kan?

let say 0/0 = infiniti?
kenapa pulak camtu?

saya takda apa nak bagi, takde orang yg nak receive it?
kenapa mesti inifiniti?

As i said in #22, infinity is just a mathematical solution for something that has no solution.

1/infinity=0 is not the right way to express that, i think...
1/x, as x approaches infinity, answer approaches 0. This is more accurate...

0/0 is infinity? i cannot think about this, from where did you get this?

consider x/x... they can be cancelled out.... whatever value of x does not bring any different answer.... you think?

Because there's just no sensible way to define it.
For example, we could say that 1/0 = 5. But there's a rule in arithmetic that a(b/a) = b, and if 1/0 = 5, 0(1/0) = 0*5 = 0 doesn't work, so you could never use the rule. If you changed every rule to specifically say that it doesn't work for zero in the denominator, what's the point of making 1/0 = 5 in the first place? You can't use any rules on it.

But maybe you're thinking of saying that 1/0 = infinity. Well then, what's "infinity"? How does it work in all the other equations?

Does infinity - infinity = 0?
Does 1 + infinity = infinity?

If so, the associative rule doesn't work, since (a+b)+c = a+(b+c) will not always work:

1 + (infinity - infinity) = 1 + 0 = 1, but
(1 + infinity) - infinity = infinity - infinity = 0.

You can try to make up a good set of rules, but it always leads to nonsense, so to avoid all the trouble we just say that it doesn't make sense to divide by zero.

What happens if you add apples to oranges? It just doesn't make sense, so the easiest thing is just to say that it doesn't make sense, or, as a mathematician would say, "it is undefined."

Maybe that's the best way to look at it. When, in mathematics, you see a statement like "operation XYZ is undefined", you should translate it in your head to "operation XYZ doesn't make sense."

excellent....

infiniti kita definasikan untuk angka yg tidak diketahui nombornya dengan pengiraan computer or apasaja peralatan pengiraan yang ada..sedangan angka itu sendiri relative pada sesuatu yang kita definisikan.. something matematik diluarkan akal manusia..

bravo... bravo...

I think infinity is jz a term used to explain something that is beyond human imagination........

like how vast this universe is or how powerful god is....

it is just beyond our mind.....  

I wonder..... now we use less than 10% of our brain.. if we use 100% can we understand what this universe is??

how many percent did human know about universe also no idea.... 1%??

aku_EnSeM

yeah.... hey... the distance of celestial objects is drectly proportional to their velocities... and once their speed surpass the speed of light relative to us, they are beyond of our observation...

okay... scientists yet to understand our observable universe... wot about the universe that is beyond of our sight?

we know 0.00001% about the universe....

don't take my words, they are exaggerated...

aku_EnSeM

the more we observe, the more theories we create, and the more complicated it is to construct a general understanding....

don't take my words, they are exaggerated....
