To paraphrase the above:
"Yeah, the problem with people who only work with Fourier series is that
they tend to forget that sin (and friends) can be used in applications
with angles that fall in a limited range, where the hardware intrinsics
produce faster and more accurate results."
I've worked on some pretty fancy DSP code in the last years, and some
spherical trig stuff. Two different kinds of code with different needs.
