Complex exponentiation is multivalued, so, since exp(i*pi/2 + 2*i*pi*k) = i, we have i^i = exp(-pi/2 - 2*pi*k) A Tribute to Euler - William Dunham. 55:08.

Euler imaginary numbers

And this path is the same as moving in a circle using sine and cosine in the imaginary plane. In this case, the word "exponential" is confusing because we travel around the circle at a constant rate. The Euler’s form of a complex number is important enough to deserve a separate section. It is an extremely convenient representation that leads to simplifications in a lot of calculations. Euler’s representation tells us that we can write cosθ+isinθ as eiθ cos θ + i sin Euler's formula can be understood intuitively if we interpret complex numbers as points in a two-dimensional plane, with real numbers along the x-axis and "imaginary numbers" (multiples of i) along the y-axis. Each complex number will then have a "real" and an "imaginary" component.

Such plots are named after Jean-Robert Argand (1768–1822) who introduced it in 1806, although they were first described by Norwegian–Danish land surveyor and mathematician Caspar Wessel (1745–1818).

This result is drummed into us so hard in various forms that it becomes second nature. In mathematics, Euler's identity (also known as Euler's equation) is the equality + = where 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. Complex numbers are sums of real numbers with multiples of imaginary number. E.g, 4+2i.
