From now on, arg(z)(z) will be considered to mean Principal arg(z)(z). Observe now that we have two ways to specify an arbitrary complex number; one is the standard way (x,y)(x,y) which is referred to as the Cartesian form of the point. The second is by specifying the modulus...

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 ...
