Applications of imaginary numbers
... We can also talk about adding a real number with a pure imaginary number. The result is called a complex number. In symbols, complex numbers are numbers of the form , where a is a real number, and is a pure imaginary number. If these numbers aren't on the number line, can we draw pictures of comple ...
