Well just wondering if any one knew of a place where i could find a proof for electricity and magnetism since it seems i will be needing a lot of these for example prove Q = Re(Ae^(i[Phi])e^(i[omega]t)) or show that I moving through a capacitor I = Re(i[omega]Ae^i[phi] e^{i[omega]t i mean looking at it, it will need eulers formula but how?
