A graphical representation of the two sinusoids v1 and v2. The magnitude of each sine function is represented by the length of the corresponding arrow, and the phase angle by the orientation with respect to the positive x axis. In this diagram, v1 leads v2 by 100o + 30o = 130o, although it could also be argued that v2 leads v1 by 230o.

It is customary, however, to express the phase difference by an angle less than or equal to 180o in magnitude.

The sinusoidal forcing function Vm cos (t + ) produces the steady-state response Im cos (t + ).

The imaginary sinusoidal forcing function j Vm sin (t + ) produces the imaginary sinusoidal response j Im sin (t + ).
