/* The computed polynomial is a variation of the Taylor series expansion for
sin(x):
x - x^3/3! + x^5/5! - x^7/7! + x^9/9! - dx*x^2/2 + dx
x - x^3/3! + x^5/5! - x^7/7! + x^9/9! - x^11/11! - dx*x^2/2 + dx
The constants s1, s2, s3, etc. are pre-computed values of 1/3!, 1/5! and so
on. The result is returned to LHS. */
