/*
Approximates the cosine of x.
Uses a taylor polynomial (roughly) accurate between 0 and
2*pi to approximate the cosine. Any values of x outside this
range are modulo'd to be within this range (you know, 'cos
cosine is cyclic).
Uses a taylor polynomial accurate between 0 and 2*pi to approximate the
cosine. Any values of x outside this range are modulo'd to be within this
range (you know, 'cos cosine is cyclic).
The taylor poly is centered at pi, with a radius of
convergence of no less than pi, making it roughly accurate
between 0 and 2 * pi. The polynomial is up to x^10, which I've
between 0 and 2 * pi. The polynomial is up to x^16, which I've
confirmed as being accurate being 0 and 2 * pi.
