Complex Numbers  Math Is Fun
The beautiful Mandelbrot Set (pictured here) is based on Complex Numbers. It is a plot of what happens when we take the simple equation z 2 +c (both complex numbers) and feed the result back into z time and time again. The color shows how fast z 2 +c grows, and black means it stays within a certain range.
Complex number  Wikipedia
A complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x 2 = −1.Because no real number satisfies this equation, i is called an imaginary number.For the complex number a + bi, a is called the real part, and b is called the imaginary part.Despite the historical nomenclature "imaginary", complex numbers are ...
Complex Numbers: Introduction  Purplemath
Now you've seen how imaginaries work; it's time to move on to complex numbers. "Complex" numbers have two parts, a "real" part (being any "real" number that you're used to dealing with) and an "imaginary" part (being any number with an "i" in it).
Intro to complex numbers (video)  Khan Academy
The imaginary part is three. One, two, three, and so on the complex plane, on the complex plane we would visualize that number right over here. This right over here is how we would visualize z on the complex plane. It's five, positive five in the real direction, positive three in the imaginary direction. We could plot other complex numbers.
