GSL implements the BSD math versions of trig and hyperbolic trig functions. IIRC these follow some standard (IEEE?) There are some reasons to use different versions (many cpus have sin, cos, sincos, exp, log and atan built in and so are faster, but don't give precisely the same results). I don't know how guile calculates these functions.
