complex number

A complex number is a number consisting of a real part and an imaginary part. Complex numbers extend the idea of the one-dimensional number line to the two-dimensional complex plane by using the number line for the real part and adding a vertical axis to plot the imaginary part. In this way the complex numbers contain the ordinary real numbers while extending them in order to solve problems that would be impossible 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 conceived complex numbers; he called them "fictitious", during his attempts to find solutions to cubic equations in the 16th century.
