I had a pure math textbook while studying but I don't recall ever referring to it for complex numbers. Mostly simple algebra.

What is your purpose? A pure math book will likely give you the theory and ignore any practical uses. I think that the polar representation is more common in mathematics.

Electronic and mechanical engineers typically use the rectangular form (unless the polar form is easier) and will usually refer to some practical use.

Mathematicians refer to a pi/2...-pi/2 rotation around the y-axis. Engineers more often use degrees (e.g. a phase shift of +/-90deg).
