5.5 The Phasor Circuit cont.

The following equations from text p.171 are useful in reconciling situations where both sinusoidal and cosinusoidal sources are present

sin(wt + q) = cos(wt + q - 90°)

cos(wt + q) = sin(wt + q + 90°)

(see example below)

If Vcos(wt + q)’s phasor representation is Þ

Then Esin(wt + f)’s phasor representation is Þ
