A complex number is any number that can be written in the form a + bi where a and b are real numbers. a is called the real part, b is called the imaginary part, and i is called the imaginary unit.Where did the i come from in a complex number ? A little bit of history!

The principal value of a complex number {eq}z {/eq} is the value for {eq}\theta {/eq} that occurs within a predefined range of values, usually, but not always, {eq}(-\pi,\pi] {/eq}. The idea of the principal value is extended to areas in complex analysis where similar ...
Complex numbers, despite the names, isn't really complicated. These are numbers which has an imaginary part and a real part. Complex numbers are expressed in the form {eq}x + iy {/eq}, where {eq}i {/eq} is equal to {eq}\sqrt {-1} {/eq}...
