Sep 19, 2010 · Oh, no, I am sorry if I was not clear. I simply don't know wherefrom they get the 2*pi*i from in e^ (z+2*pi*i). The information I get is what I've written. I believe that the 2*pi refers to the period. It just seems kind of abrupt to randomly insert it without any proof or reference to hardly anything.. Sep 19, 2010.

Für ergibt sich aus der eulerschen Formel die sogenannte eulersche Identität ,die einen einfachen Zusammenhang zwischen vier der bedeutendsten mathematischen Konstanten herstellt: der eulerschen Zahl , der Kreiszahl , der imaginären Einheit sowie der reellen Einheit . Die folgende umgeformte Variante der Gleichung wird bisweilen – obwohl komplizierter …

Fundamentally, Euler's identity asserts that is equal to −1. The expression is a special case of the expression , where z is any complex number. In general, is defined for complex z by extending one of the definitions of the exponential function from real exponents to complex exponents. For example, one common definition is:

Homework Statement The problem at hand is that I don't understand wherefrom my text book got a certain term(e^(2*pi*i). It doesn't say.

e^(2 pi i) = e^0 = 1. One can also obtain the classical addition formulae for sine and cosine from (8) and (1). All of the above extensions ...

e is Euler's number, the base of natural logarithms, i is the imaginary unit, which by definition satisfies i 2 = −1, and π is pi, the ratio of the circumference of a circle to its diameter. Euler's identity is named after the Swiss mathematician Leonhard Euler.

To try and make that more LI5ish, 2pi is a special value when you look at sin and cos functions. That means that when you put it into the above ...

e^(2 pi i) = e^0 = 1. One can also obtain the classical addition formulae for sine and cosine from (8) and (1). All of the above extensions have been restricted to a positive real for the base.

Originally Answered: If e^ (2pi*i) = 1, does this mean that e^ (2pi*i) = e^0? So, 2pi*I = 0? Complex logarithm showing the need for multivalued logs.

e is Euler's number, the base of natural logarithms,: i is the imaginary unit, which by definition satisfies i2 = −1, and: π is pi, the ratio of the ...

exp(z+2πi), = exp(z)exp(2πi), Exponential of Sum: Complex Numbers. = exp(z)×1, Euler's Formula Example: e2iπ.

Euler's formula, named after Leonhard Euler, is a mathematical formula in complex analysis that establishes the fundamental relationship between the trigonometric functions and the complex exponential function.Euler's formula states that for any real number x: = ⁡ + ⁡, where e is the base of the natural logarithm, i is the imaginary unit, and cos and sin are the trigonometric functions ...

e^(2 pi i) = e^0 = 1. One can also obtain the classical addition formulae for sine and cosine from (8) and (1). All of the above extensions have been restricted to a positive real for the base. When the base x is not a positive real, it is not as clear-cut how to …

There is nothing wrong with your argument. According to the Euler's formula, we have eiθ=cos(θ)+isin(θ). Thus e2πiα=cos(2πα)+isin(2πα).

A way to visualize this would be to use the definition e = (1+1/N) N and subsequently e x = (1+x/N) N. If you start plotting this for x = 2 pi i and increasing N's you can see how the expression converges to 1.

i = e i π /2. Thus. i i = (e i π /2) i = e i 2 π /2 = e-π /2. Thus i i is a real number! In decimal form it is approximately 0.207880. Here is a more algebraic way to see it. De Moivre showed that e ix = cosx + isinx so that e i π /2 = cos(π /2) + isin(π /2) = i, for example.

Why is e^(pi i) = -1? Asked by Brad Peterson, student, Roy High on January 29, 1997: I was watching an episode of The Simpsons the other day, the one where Homer gets sucked into the third dimension, and in this 3-D world, there was an equation that said .
