converting phasors to sinusoids

[SeanHatch]

Can anybody give me a hint on this one? I can convert simpler examples, so if you can at least tell me how to make it recognizable I'd be greatful.

(8-j3)5e^something.

Your question is a bit vague. To convert a phasor to a sinusoid, you need the phase angle and magnitude ie. convert rectangular to polar.

eg. 3+j4 has a magnitude of 5 and a phase angle of phi = artan(3/4)

so it is 5 sin (wt - phi) where w = 2 pi f
