Calculating Pi 1.MP4

Did you ever wonder where the numerical value for pi came from? This video shows a simple method, first used by Archimedes, to estimate the value of Pi. It is based on simple trigonometry and is easy to understand graphically.

Great, answers a good question understandably. Keeps nerds like me entertained.

@picklezero Entertaining nerds - good work if you can get it ;-)

like they use a triangle to calculate pi..... pi = 3.14159265.... lol 1=144,000 2/144,000 =72000 ===== 3/144,000 =48000 triangle reference 4/144,000 =36000 square reference 5/144,000 =2880 pentagone 6/144,000=2400 hexagon 7/144,000= 2057.1428 .....a Reference point your 2 equal parts… triangle error 8/144,000=18000 hexagon 9/144,000=16000 pentagon ends 10/144,000=14400 square ends…. 11/144,000=13090.9090909090909­090909090909090 ….error triangle

1 k'atun = 20 tun 7,200

now x that by 5 you get 36000...... pi

now you can build a 5 side pyramid

so a base pyramid would have 144,000 stones 36000 by 36000 by 36000 by 36000

see the native amarican pi.... and you cant build pyromids without pi

[ZorroIsGod1]

you need a 5 base math dymetion math....... a stone a stick and seashell.....

Representation Long Count subdivisions Days ~ solar years

0.0.0.0.1 1 k'in 1 1/365

0.0.0.1.0 1 winal = 20 k'in 20 0.055

0.0.1.0.0 1 tun = 18 winal 360 0.986

0.1.0.0.0 1 k'atun = 20 tun 7,200 19.71

1.0.0.0.0 1 b'ak'tun = 20 k'atun 144,000 394.3

see.... pi 3.144000

it took 400 years to validate..... 360 to comeback in full circle using night and light as your ruler..... k'atun is the one part of 360.

i dont understand how the where N sin (x/2)<Pi<N sin (x/2) comes from 

[aak711]

Now I understand what value of pi actually means: its to calculate the length of the circumference of a circle. Of course.

I should have known this earlier.

Thank you very much.
