| - Requires: Polar coordinates, Polynomial function Starting from the solution of the third degree equation... it yields \sqrt{-1}!!! Reach de Moivre's formula Now read: Complex exponential
* New terms Complex number, Imaginary number (part, unit), De Moivre's formula
- Complex numbers are a special data-type that represents the classical complex numbers with it's real and imaginary parts. Note that Python uses the notation of electronics to write something like c1 = 5 + 2j
- From Wikipedia, the free encyclopedia (Redirected from Complex numbers)[1][2]A complex number can be visually represented as a pair of numbers (a,b)forming a vector on a diagram called anArgand diagram, representing the complex plane. Re is the real axis, Im is the imaginary axis, and i is the imaginary unit, satisfyingi2 = −1.

- From Wikipedia, the free encyclopedia (Redirected from Complex numbers)[1][2]A complex number can be visually represented as a pair of numbers (a,b)forming a vector on a diagram called anArgand diagram, representing the complex plane. Re is the real axis, Im is the imaginary axis, and i is the imaginary unit, satisfyingi2 = −1. A complex number is a number which can be put in the form a + bi, where a and b are real numbers and i is called the imaginary unit, where i2 = −1. In this expression, a is called the real part and b the imaginary part of the complex number. Complex numbers extend the idea of the one-dimensional number line to the two-dimensional complex plane by using the horizontal axis for the real part and the vertical axis for the imaginary part. The complex number a + b'ican be identified with the point (a, b). A complex number whose real part is zero is said to be purely imaginary, whereas a complex number whose imaginary part is zero is a real number. In this way the complex numbers contain the ordinary real numbers while extending them in order to solve problems that cannot be solved with only real numbers. Complex numbers are used in many scientific fields, including engineering, electromagnetism, quantum physics, applied mathematics, and chaos theory. Italian mathematician Gerolamo Cardano is the first known to have introduced complex numbers. He called them "fictitious", during his attempts to find solutions to cubic equations in the 16th century.
