Guest Posted September 17, 2008 Report Share Posted September 17, 2008 You can use only paper and pencil. And infinite time. No other material. And you know math as much as an elementary school student. Can you tell me nearly the exact pi number after nearly infinite time? Quote Link to comment Share on other sites More sharing options...
0 Guest Posted September 24, 2008 Report Share Posted September 24, 2008 Of course I didn't make my computer to calculate all 4 quadrants. In fact, I considered x-y analitic plain, and only the points from (0,0) to (+n,+n). But this way may require more math knowledge, thus I wanted to tell my method in square and circle way. It got time but I'm happy to manage to make someone understand my simple method. Thanks to everybody. I am not sure how your method would actually work, and maybe I missed how the points to be considered are generated. You can get infinite points to evaluate by assuming x=1 and y =1 and then y increments such as 1.01, 1.001, 1.0001, 1.00001,..... As you can see one would evaluate an infinite number of points and get no where near to pi. Help! Quote Link to comment Share on other sites More sharing options...
0 Guest Posted September 24, 2008 Report Share Posted September 24, 2008 Use buffon's method. You could draw several lines, each line, the length of the pencil apart, throw the pencil on the lines (lots of time, remember we have infinite time), then using the number of times the pencil crosses the line, calculate PI.

How big a chessboard you make, so much you get close to pi. I don't remember precisely, but maybe I had worked on a 1 million x 1 million chessboard, and reached only the 7. decimal of pi. I couldn't understand why you think that I will get no where near to pi??? Use buffon's method.

(http://mathworld.wolfram.com/BuffonsNeedleProblem.html) I wrote before about that method. It is a magic way and I like and admire it very much. But I asked a method other than it, by only calculations. Quote Link to comment Share on other sites More sharing options...

You can evaluate an infinite number of points within a square a get nowhere as I have shown in the determination of points to evaluate. However by choosing a predetermined sized chess board, and only evaluating the points of intersection of rows and columns I see how it could work. Thanks.

0 Guest Posted September 27, 2008 Report Share Posted September 27, 2008 I still don't see how to do this...but... 22/7 is an approximation but is usually used to make it easier to understand (hearing about an unknown number in grade school was probably one of the strangest things I ever heard...) Usually, in math (I guess in certain types) you just use the Pi symbol itself, which doesn't give much of an answer.. (but makes it easier to use) I guess I will have to agree with some others about how it can't be simple division between two numbers or so... Probably because they will become a repeating decimal at some point (an assumption) Oh and I find it annoying to calculate any equation with 22/7, since a number divisible to 7 usualy never appears and 22 is a pretty high number... (That's why I just use Pi symbol, unless I really needed an answer..) (Then I use a calculator, which also isn't very accurate...) Truthfully, I do not see how it is actually possible to calculate Pi correctly (accurately...) Quote Link to comment Share on other sites More sharing options...
