Complex numbers, polar form & basic operations. Chris Tisdell UNSW Sydney

I discuss a simple example and show how to perform basic calculations involving the polar form of a complex number. Such ideas are seen in high-school and first-year university mathematics.

Complex numbers are an extension of the well--known real numbers. Complex numbers (and complex--valued functions) find useful applications in: signal analysis; fluid mechanics; relativity; and quantum mechanics.
A solid understanding of basic calculations with complex numbers empower us to do more significant and interesting things with them.
