Seeing as I wasn't alow'd to post for 10 days for pyramids that's gonna have to be my vote.

whoever asked a long time ago how to calculate pi, it is the same as 22/7.

FOR THE LOVE OF GOD, NO!
22/7 = 3.142857 (six repeating decimals)
pi = 3.14159265358......
er, pi = 4.

YAY! You're back!!!!!!!!!!!!!!!! :-D

I remember pi = 4!!!!(<-- not factorials) In fact, I was just thinking of that last night, for some odd reason.

PI = 4. AYBABTU.

1/7 can be calculated using the following method:
1. start with .14
2. the next two digits are double that (28)
3. the next two digits are one more than double that (57) (this is because if you double 56, you get 112, so the 1 carries into the 6 making seven)
4. continue this process

I FIGURED THIS OUT ON MY OWN when I saw the 14,28,almost 56 pattern...
1/7 =
_14 (7*2)
+__28 (14*2)
+____56 (28*2)
+_____112 (56*2)
+_______224 (etc..)
+_________448
+___________896
+____________1792
+______________3584
=142857142857142784
compared to 1/7 which is
.142857142857142857...
I love making things overly complicated :)

d00d, j00 43r 1337!
I'm going to see if I can figure out why that's true. That's really cool :)
14*1/100 + 14*2/10000 + 14*4/1000000 + ...
Sum n=0 to infinity: 14(2)^n/(100^(n+1)) = 1/7?
Or would it be written better as
Sum n=0 to infinity: 14(2)^n/(100(100)^n) = 1/7?
Okay, that reduces to:
7(1/50)^n/50 or 7(1/50)^(n+1)

Okay, so there's the fractional part of what you wrote...
7(1/50)^0 = .14
7(1/50)^1 = .0028
7(1/50)^2 = .000056
...
7/50, 7/2500, 7/125000, 7/6250000, ...
Ooh! I know... the Sum of 7(1/50)^(n+1) from 0 to x is 1/7-(1/50)^x/350
And lim x->infinity: 1/7-(1/50)^x/350 = 1/7 //!!!

Good thing I had my TI-89 sitting beside me

You can just say "1/7\!" Then the "!" is treated like a "!" and not a factorial :) Escape characters rule

I love escape characters.\nThey're 1337\!\n

Not only is that random, it is wrong.

It's less wrong than [link].

WHAT!?!?!?!? You did not... no...

No please...

You did not just write that pi=22/7.

Die.

We should spam him with a million digits of real pi every 30 secounds.

I could get him up to around an hour.

Who else is with me???

...From memory?...

Good God, no!!! I got a program that can tell you as many digits of pi as you want. I haven't done it in a while, but the last time I did it, I got 128,000,000 digits in around 2 hours.

Yes! That's awesome! Hahaha! Let's spam him! :-D

...Ready...Set...Go!...*immediately opens email program and spams*

Me!

I sent one!

I tried to send all mine at a time, but my computer froze and just sat there... so i shot it

:-)

With what?

a .270 bolt-action rifle to be exact... i couldnt get on it for a week after that.

Wow........ ;-)

I'm sending one right now! :-D

...

Done!

I sent one too (not a million digits though). :-D

I saved my outgoing message, it was really funny :-D I had all this random 13375p34k stuff and after I had 10,000 digits (joyofpi.com), I wrote "AND IN CASE YOU FORGOT THEM ALREADY, HERE THEY ARE AGAIN!"

Hehe, this guy is going to hate us :D:D:D

This is really mean. *sends another ten*

I've sent three with the first 100 digits in binary. *sends some more.*

Did you use actual binary or just BCD?

He probably used something like [link].

I've sent about ten. 120d, I hope he doesn't report an abuse of e-mail through ticalc.org. That would stink.

Well, one thing's for sure, he'll never forget that pi!=22/7 //!!

"pi!"...can you do that? *Checks*
pi! = 7.18808272898 according to my HP49g...not 22/7 ;) j/k

*YES*!!! There's something else the HP3x/4x calcs can do but the TI 89 cannot do directly. The Factorial function does have a definition for non-positive-integer values; it is defined across the entire number space by the gamma function ...

(something like x! = gamma(x-1) or something like that)

*checks HP 39G and HP 48G+ and HP 49g+, and all of them do it*

And apparently the TI calcs don't know that. I don't think they even have the gamma function, so you can't even get at it from the back door.

Oh yeah, the gamma function. I really think the TI calcs should have that. At least they recognize that it is possible to do the factorial (it might return something like (.5)!) but it won't solve it :( Fortunately, google will, and so will windows calculator.

Now THAT was a dumb typo. Haha, I don't know how that exclamation mark got there... but you're right, you can take a factorial of nonintegers. Dang.

it wasn't a typo. if taken the way it was taken it would have to be pi!==22/7, unless i confused myself and don't know what the conversation was about

No, we were saying that pi != pi! because of the factorial. pi! is ~7.18808273... while, well... you know what pi is.

But I know what you mean about the equals signs. QB programmers don't need two ;-) It's just Javascript, Java, C, C++, and probably a whole bunch of other languages, that use ==...... :-D

what you meant is "pi != 22/7" or "pi doesn't equal 22/7"...that's where the "!" came from... I jjust thought I would try to be funny... ;)

Oops, I read it as pi!!=22/7.

/me needs to keep his contacts in

Hehe, that was a good one ;-)

I sent about 6 total. :-D

Just sent one with an attachment with 1 million digits :^) I could do this all day!

if pi=22/7, then pi*7=22, so on your 22nd birthday you should get seven pies, but that usually doesn't happen, so pi != 22/7...my logic...BTW, if x=4 and y=7 in problem number 1, and x=-2 and y=5 in problem 2, then obviously x and y are always changing, so WHY DO WE NEED TO KEEP FINDING OUT WHAT THEY EQUAL?!?!

Did you take your medicine this morning????

I know! x just won't keep its identity! It keeps changing itself like it's a secret agent...

OH WAIT... NOW WE FIGURED OUT THE KEY TO ALGEBRA

AGENT X IS REALLY AN ASSASSIN AND WE NEED TO GET OUR 1337 MATH SKILLZ GOOD ENOUGH SO WE CAN HUNT AGENT X DOWN AND KILL HIM! HAHAHAHAHA!

(This is what being up past midnight does to me ;-))

People like you are the reason people like me are on medication

-some person I dont know

120d, that's good :)

How can you call [him] good? Who is good but God alone?
-Jesus (and a little editing)

... and God looked out at all he had created and said 120d is good :)

I think he said that everything was "900|)" not "good"

But somewhere in the translations, the 1337 part of it got lost. :( So now it's just recorded as "good." 120d

No, he said "d42n 4m i 1337!!!!". :-D

That is awesome! You know, I never got my posting priveleges held back, amazingly enough. *thanks staff* I deserved it a couple times :)

You are lucky...you haven't don it since I got the ability to do so. I will have to admit "Lewk_of_Serthic" didn't complain at all and took it very well.

LOL, I knew when to stop. :)

:p

My e-mail wasn't working. :-D I deserved it and I'm a big boy.
