The NUMBER PI

There are many forms of PI and you can see them [1]

However the number of Pi is not just a circle but a series of geometric images such as an equilateral triangle, square, pentagon, etc. unique pattern that I found 2004. Pi for all numbers is:

$\pi _{n}={\frac {n}{2}}.sin({\frac {360}{n}})$

sinus in degrees

n= {3,4,5,6........., infinity}

n=3 it is the equilateral triangle

$\pi _{3}={\frac {3}{2}}\sin({\frac {360}{3}})$

$\pi _{3}=1.299038105676657970145584756129404275207103940357785471041855234588949762681600027810859640067936431756719606061555027272477458821249214359108741634070780236396069923926729186550981115075813506192448761484257450177492164988004191001691378478420285348745275896191014287489903034894542100737760629932038067463761097204575710701640392743812359372142969874748342368381216535847874688010418122988440891548250968547863765249583132380335670783737076566229143676252517640533358216521993217274347815376373554674619972363212265589806452991554023153186737988373546994737255879027157790435027172484077780448014436830076173399466281730856066512557064076779745703123294923844606990748216673347110878468792671641139677682025389606048286479258495794767292154648948115366998523815015896613116458830885964900880276393737512516970811610634553457857999822195125972183078771421332595361479060232409486838841413231534260410498721433971667217832916432192792394148303696921223601631524640287512203987208937787304127.......$

Area of an equilateral triangle will be

$R^{2}\pi _{3}$

R -radius of the circle described about an equilateral triangle

The scope of the triangle will be

$C={\frac {2R\pi _{3}}{\cos {\frac {\alpha }{2}}}}:\alpha ={\frac {360}{3}}$

See picture[]

n=4 it is a square

$\pi _{4}=2$

Area of squares will be

$R^{2}\pi _{4}$

R -radius of the circle described around the square

Perimeter of the square will be

$C={\frac {2R\pi _{4}}{\cos {\frac {\alpha }{2}}}}:\alpha ={\frac {360}{4}}$

For the numerical values ​​of PI recommend free extra precision calculator Harry-J-Smith XP,XM,….. recommend m=1.0E+10000000 to the success of the calculator you need to install netframework2.0
