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.

No. Say your matrix is called A, then a number e is an eigenvalue of A exactly when A-eI is singular, where I is the identity matrix of the same dimensions as A. A-eI is singular exactly when (A-eI)T is singular, but (A-eI)T=AT-(eI)T =AT-eI. Therefore we can conclude that e is an eigenvalue of A exactly when it is an eigenvalue of AT.
[pi^(1/3)]^2 * pi = pi^(2/3) * pi = pi^(5/3) The answer is the cubic root of pi to the fifth power.
(pi + pi + pi) = 3 pi = roughly 9.4248 (rounded) Well, if you use the common shortened version of pi which is 3.14 and add that 3 times, you get 9.42.

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].
When doing roots of imaginary or complex numbers, it's best to work in polar form.A little background first.A complex number is represented by a magnitude and an angle. This comes from Euler's Formula (see related link): eiΘ = cos(Θ) + i sin(Θ) {Θ is in radians}. Note that both eiΘ and [cos(Θ) + i sin(Θ)] have a magnitude of 1, so multiply by the magnitude: AeiΘ = Acos(Θ) + Ai sin(Θ).Now if you have a number [a + bi], the angle Θ = arctan(b/a), but this will give Θ between -pi/2 and pi/2 (-90° & +90°). So to get the other angles, you need to figure what quadrant the complex number is in. If a is positive, then it is left of the imaginary axis and your angle is fine. If a is negative, then you need to add 180° (pi radians) to the angle. Or you can subtract pi radians as well. This works because the 180° turn is on the same line with the same slope, just pointing in the opposite direction. To get the magnitude A, just do sqrt(a2 + b2). Now this is for general complex numbers. The question asked for imaginary numbers, which a = 0, and Θ will be pi/2 for positive imaginaries (b>0) or -pi/2 for b

: ; Euler's identity http://en.wikipedia.org/wiki/Leonhard_Euler some pretty hardcore math, but is important in alot of different ways.
"Capture" is a homophone for "captured" containing "ei".
if you can't collect EI after 65 do you have to pay EI after 65
