Complex Numbers: An Introduction
A complex number can be expressed in the form:
- a + bi
where a and b are real numbers.
The number i is defined as the square root of -1. It is an imaginary number, since the square root of any negative number is not a real number.
Complex numbers are not algebraic expressions. They are numbers, containing a real part (a) and an imaginary part (bi).
