## Guyofreckoning 2 years ago How do I reach Pi again? I kinda forgot and now I have a serious problem. <_> Help please.

1. Brittni0605

What is the problem?

2. Guyofreckoning

xD Of course you would answer first that's very nice, actually I'm just trying to remember because my teacher is going to have us work on cylindrical volumes again. just a review... I don't wanna be behind in class like that.

3. Brittni0605

Oh, okay, I wont answer you anymore then.

4. Guyofreckoning

heh, don't joke like that.

5. Brittni0605

Im serious, Why do you think im joking?

6. Guyofreckoning

lol cause I didn't quite say anything offensive... I don't think I did at least...

7. Brittni0605

You said "of course you would answer first..."

8. Guyofreckoning

xD Of course you would answer first that's very nice... that's very nice... nice

Oh ok, I thought you were being sarcastic :/ ..but im sleepy. I'm signing off, going to bed, goodnight @Guyofreckoning

11. Guyofreckoning

Night. Take it easy.

12. malical

Well... What is the problem? :)

13. Guyofreckoning

just needa remember the equation to get to Pi...

14. wio

You want to approximate $$\pi$$?

15. Guyofreckoning

yeah. something with division and circles, can't remember the thing for the life of me.

16. wio

Well pi is the ration between the circumference (perimeter of circle) and the diameter.

17. Guyofreckoning

ok I think I can do this now, dumb old me forgot about google. heh... but thanks anyways!

This converges to $$\pi$$. Start now and in your lifetime you might get it to like 5 decimal places :P$\pi= 4 \sum_{n=0}^{\infty} \frac{2}{(4n+1)(4n+3)}$Seriously though $$\pi$$ is just $$\pi$$. It should always be kept as that unless you want a decimal approximation of something. in that case $$\pi$$ is just what you can memorize. You can't compute the decimal value of pi because it is irrational.

O: I dunno if I should be so mean as to switch the best result. but that is one heck of a reply

20. Guyofreckoning

sry wio :c but that is the best reply.
