Definition
Euler's formula indicates that sinusoids can be represented mathematically as the sum of two complex-valued functions:
or as the real part of one of the functions:
As indicated above, phasor can refer to either or just the complex constant, . In the latter case, it is understood to be a shorthand notation, encoding the amplitude and phase of an underlying sinusoid.
An even more compact shorthand is angle notation:
