this is actually cos^2+sin^2=1 in this context,
these are not unity vextors, if you square the cosine and sine part you don't get one, but a square of the amplitudes, so it is more cos^2+sin^2=amplitude^2
i mean cos and sin the functions, not the components. You get the component equation by multiplying the whole equation by amplitude^2. I said it as cos^2+sin^2=1 because that's the trigonometric identity as taught in grade 11 or so.
