Yes, I had scoping with something like With[] in mind when I said "evaluate the cosine once as a common subexpression". Putting the expression in Horner form additionally cuts down on the multiplications needed.

Good one, many-gravatared one! For speed, one might perhaps further save on cycles with a With[{cos=Cos[t]},...] or similar.
