One potential problem with your suggestion is that the "cycles" optional
argument seems to be being expressed in floating point, and because some
numbers cannot be expressed exactly in floating point, (sin x degrees)
might end up having some error that it would not have if sind were
explicitly defined. I guess if (equal degrees 360) there is no problem
with degrees themselves but I'm still concerned about the general problem.
