So, Euler's formula is saying "exponential, imaginary growth traces out a circle". 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.

More details. (Complex numbers can be expressed as the sum of both real and imaginary parts.) i is an exceptionally weird number, because -1 has two square roots: i and -i, Cheng said. "But we can't tell which EULER’S FORMULA FOR COMPLEX EXPONENTIALS According to Euler, we should regard the complex exponential eit as related to the trigonometric functions cos(t) and sin(t) via the following inspired deﬁnition: eit = cos t+i sin t where as usual in complex numbers i2 = ¡1: (1) The justiﬁcation of this notation is based on the formal derivative A geometric plot of complex numbers as points z = x + jy using the x-axis as the real axis and y-axis as the imaginary axis is referred to as an Argand diagram. 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). Representation of Waves via Complex Numbers In mathematics, the symbol is conventionally used to represent the square-root of minus one: that is, the solution of (Riley 1974). A real number, (say), can take any value in a continuum of values lying between and . On the other hand, an imaginary number takes the general form , where is a real number.

Geometrically, it can be thought of as a way of bridging two representations of the same unit complex number in the complex plane. Logarithms of Negative and Imaginary Numbers By Euler's identity, , so that from which it follows that for any , . Similarly, , so that and for any imaginary number , , where is real. Finally, from the polar representation for complex numbers, where and are An imaginary number is a complex number that can be written as a real number multiplied by the imaginary unit i, which is defined by its property i2 = −1. The square of an imaginary number bi is −b2.

### 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.

We introduce the symbol i by the property i2 ˘¡1 A complex number is an expression that can be written in the form a ¯ ib with real numbers a and b.Often z is used as the generic letter for Euler’s Identity. In order to describe the Fourier Transform, we need a language. That language is the language of complex numbers. Complex numbers is a baffling subject but one that it is necessary to master if we are to properly understand how the Fourier Transform works. Complex Number Calculator.
