Definition of Complex Number
The complex numbers were introduced to provide a number system in which every number (positive or negative) has a square root.
The introduction of the imaginary number \(i = \sqrt{-1}\) accomplished this purpose.
Each complex number can be written in the form \(a + ib\), where \(a\) and \(b\) are real numbers, which can be zero.
We call \(a\) the real part of \(a + ib\), and \(b\) the imaginary part of \(a + ib\).
All real numbers are complex numbers.
Some examples of complex numbers are \(1 - i\), \(2 + 3i\), \(-3.5i\) and \(17\).
