some pretty hardcore math, but is important in alot of different ways.
The number for pi is: 3.1415926535897932384626433832795
Do you mean pi? pi = 3.1415926535 Circumference of a circle = pi*diameter

No, since Pi is an irrational number, 2(pi) would still be irrational.
[ln(2) + i*pi]/ln(10) if you are referring to log as a base 10 log. ln refers to thenatural logarithm (log base e)The log of any negative number is imaginary. The formula above is derived fromthe relationship:-1 = ei*pisince you want log of -2, multiply both sides by 2-2 = 2*ei*pitaking natural logarithm of both sides: ln( -2) = ln(2*ei*pi ) = ln(2) + ln(ei*pi )which reduces to ln(2) + i*piIf you want log10 then divide both sides by ln(10)So log10(-2) = ln(-2)/ln(10) = [[ln(2) + i*pi]/ln(10)x = log (-2) = log10(-2)10x = -2Think about the smallest possible number you can put in for x.10-∞ = ?10-∞ = 1/10∞10∞ = ∞1/∞ = ?1/∞ = 0It is impossible to ever get 0 or a negative number because you will never reach infinity.log(-2) is undefined
by euler: i=ei(pi)/2 therifore ii = (ei(pi)/2)i=ei^2(pi)/2=e-(pi)/2 ~0.208
4 The formula for circumference is 2*pi*radius, or pi* diameter. since it is 4*pi, just divide by pi.
pi you bi ei
"Yo" is not a Portuguese word. It is a Spanish slang interjection used to get someone's attention or to express enthusiasm. In Portuguese, a similar expression used to get someone's attention is "ó" or "ei".
Euler's formula states that: eix = cos(x) + i*sin(x); where "i" is an imaginary number and "x" is an angle value. Under this reasoning, ei*2(pi) equals 1: ei*2(pi) = cos(2(pi)) + i*sin(2(pi)); ei*2(pi) = 1 + i*(0); ei*2(pi) = 1 + 0; ei*2(pi) = 1. Another contributor: Equivalently, e2i*pi - 1 = 0 That statement brings together, in such simplicity, two of the most important transcendental numbers (e and pi), the basic element of complex mathematics (i) and the two identities of arithmetical operations: addition (0), and multiplication (1).
Nobody can prove it because it is not true. It is a real number, though. eix = cos(x) + i*sin(x) Therefore ei*pi/2 = cos(pi/2) + i*sin(pi/2) = 0 + i*1 = i Raising both sides to the ith power, (ei*pi/2)i = ii So that ii = ei*i*pi/2 = e-pi/2 = 0.2079. Gelfond proved that the above value is irrational [transcendental, actually].
oni, sa na ei yo.
"ein Ei" is "an egg" in English.
Ei. Pronounced EYE
Circumference of any circle = 2*radius*pi or diameter*pi

After a thorough search, I have found nothing called El pi. Perhaps the person asking the question means what is Pi? In that case, it is a mathematical constant calculated by the ratio of a circle's circumference to its diameter. It is equal approximately to the value 3.14159.
