Still, the discussion is only about convenience. For example, e^ix = cos x + i sin x (with sin/cos taking an argument in radians) would become e^ix = cos 2pi x + i sin 2pi x (with sin/cos taking an argument in turns). It's more cumbersome than the radian-based definitions, but it's not strictly different.


As mentioned elsewhere in this thread, with turn-based rotation units, this relationship can be simplified to avoid transcendental numbers entirely:

> (-1)^(2x) = cos(x) + i sin(x)
