WitrynaA complex number is a combination of a real number and an imaginary number, taking the form of x + iy, where x and y are real numbers. For example, 12 – 5 i is a complex number. However, when x = 0, leaving only iy, such as 16 i, it is then called a purely imaginary number. In contrast, if y = 0 leaving only x, the complex number is then a ...
