No. It's more what the previous poster said about encoding rotation. It's just not a xyz axes. It's current, charge, flux as axes. The trig is how you collapse the 3d system into a 2d or 1d projection. You lose some information but it's more useful from a spefic reference.
Without complex numbers you can't properly represent the information.
The natural representation would be the transient solution u(t) or i(t). Harmonic solutions are merely a special case, for which it turned out complex numbers were useful (because of the way they can represent rotation). They certainly serve a purpose there, but imo this is not an instance of 'complex numbers appearing in nature'.
