phasor2(ff)

phasor2(ff) creates a movie illustrating a pair of phasors rotating at ff Hz.

phasor2(ff) creates a movie illustrating a pair of phasors rotating at ff Hz. The positive frequency member rotates in a counter clockwise direction. The negative frequency member rotates in a clockwise direction. The user can click a continue/pause button to view the phasor's relative position at any moment in time. A projection shows the sinusoidal waveform that results from the summation of these phasors. It is suggested that ff = 0.03 Hz makes for a rotation speed that is slow enough to follow.
