Just as you can express impedance as a complex number you can also express voltage and current waveforms in complex notation using the Euler Identity.

You should also review some material on Phasors

http://en.wikipedia.org/wiki/Phasors

that should keep you off the streets for at least an afternoon.

Don't forget to check the e-book pages on this forum
